Reduction of the heteroleptic metal carbonyl complex Mo(CO)3(η5-Cp)H with the metallic salt Cs5Bi4 in the presence of [2.2.2]crypt (= 4,7,13,16,21,24-hexa­oxa-1,10-di­aza­bicyclo­[8.8.8]hexa­cosa­ne) in liquid ammonia led to single crystals of bis­[(4,7,13,16,21,24-hexa­oxa-1,10-di­aza­bicyclo­[8.8.8]hexa­cosa­ne)caesium] penta­carbonyl­molybdate, [Cs(C18H36N2O6)]2[Mo(CO)5] or [Cs([2.2.2]crypt)]2[Mo(CO)5]. The twofold negatively charged anionic complex corresponds to the 18 valence electron rule. It consists of an Mo atom coordinated by five carbonyl ligands in a shape inter­mediate between trigonal–bipyramidal and square-pyramidal. The Mo—C distances range from 1.961 (3) to 2.017 (3) Å, and the C≡O distances from 1.164 (3) to 1.180 (4) Å.

Structure description

Synthetic routes and structural compositions of neutral metal carbonyl complexes for group 4 to 11 as well as negatively charged carbonyl metalates for group 4 to 10 are well known in the literature, and are extensively documented (Holleman et al., 2016[Holleman, A. F., Wiberg, E. & Wiberg, N. (2016). Anorganische Chemie - Band 1: Grundlagen und Hauptgruppenelemente, 103rd ed., pp. 2108-2122 and 2130-2135. Berlin: De Gruyter.]). For a detailed review of metal carbonyl anions, see: Ellis (2003[Ellis, J. E. (2003). Organometallics, 22, 3322-3338.]). Only very recently, the first tricarbonyl nickelate, [Ni(CO)3]2–, could be synthesized via the reaction between Ni(CO)2(PPh3)2, K6Rb6Ge17 and chelating ligands in liquid ammonia (Lorenz et al., 2018[Lorenz, C., Kaas, M. & Korber, N. (2018). Z. Anorg. Allg. Chem. 644, 1678-1680.]). Thus, it was again demonstrated that Zintl phases are suitable for the reduction of metal carbonyl complexes. This behaviour has previously been exemplified in the reduction of Mn2(CO)10 by K4Ge9 to yield [Mn(CO)5]− (Härtl, 2012[Härtl, O. (2012). PhD thesis. Universität Regensburg, Germany.]). In the field of group 6 homoleptic carbonyl metalates, crystal structures determined by single-crystal X-ray diffraction experiments are sporadically documented. The first crystal structure comprising [Cr(CO)5]2– and documented in the Cambridge Crystal Structure Database (Groom et al., 2016[Groom, C. R., Bruno, I. J., Lightfoot, M. P. & Ward, S. C. (2016). Acta Cryst. B72, 171-179.]) resulted from the reaction between Cr(CO)6, [2.2.2]crypt and the nominal phase K3Cd2Sb2 in ethyl­enedi­amine (Zhai & Xu, 2011[Zhai, J. & Xu, L. (2011). Acta Cryst. C67, m202-m204.]). Previously, in 1985, the heavier homologue [W(CO)5]2– was obtained in the reaction between W(CO)2(NMe3), NaC10H8 and [2.2.1]crypt (Maher et al., 1985[Maher, J. M., Beatty, R. P. & Cooper, N. J. (1985). Organometallics, 4, 1354-1361.]). Using the same route, the corresponding Mo species could be synthesized, but there was no documentation of its structural characterization (Maher et al., 1982[Maher, J. M., Beatty, R. P. & Cooper, N. J. (1982). Organometallics, 1, 215-217.]). To our knowledge, there is no detailed structure data of the [Mo(CO)5]2– anion published so far. We here present the synthesis and crystal structure of the penta­carbonyl molybdate complex [Cs([2.2.2]crypt)]2[Mo(CO)5].

[Cs([2.2.2]crypt)]2[Mo(CO)5] was obtained by the reduction of Mo(CO)3(η5-Cp)H with Cs5Bi4 in the presence of [2.2.2]crypt in liquid ammonia. The asymmetric unit contains two [Cs([2.2.2]crypt)]+ cation complexes and a twofold negatively charged [Mo(CO)5]2– unit which follows the 18 valence electron rule (Fig. 1[link]). The Mo—C bonds in the anionic unit range from 1.961 (3) to 2.017 (3) Å and the C≡O bonds from 1.164 (3) to 1.180 (4) Å. The former bonds are slightly shorter and the latter bonds are slightly longer than the corresponding bonds in Mo(CO)6 (Mak, 1984[Mak, T. C. W. (1984). Z. Kristallogr. 166, 277-282.]). This can be explained by the high π-acceptor characteristics of the carbonyl ligands, which leads to a partial electron transfer into their π* orbitals and consequently to a weakening of the C≡O bonds. As expected, this effect is stronger in the negatively charged penta­carbonyl molybdate than in the neutral complex. The [Mo(CO)5]2– anion shows a shape inter­mediate between a trigonal bipyramid (TP) and a square pyramid (SP) (τ5 = 0.49; extreme forms: τ5 = 0 for SP and 1 for TP; Addison et al., 1984[Addison, A. W., Rao, T. N., Reedijk, J., van Rijn, J. & Verschoor, G. C. (1984). J. Chem. Soc. Dalton Trans. pp. 1349-1356.]), with the following C—Mo—C angles: C1—Mo1—C2 = 168.11 (11)°, C3—Mo1—C4 = 108.89 (13)°, C3—Mo1—C5 = 112.35 (13)°, C4—Mo1—C5 = 138.76 (14)°. The carbonyl ligands point almost linearly towards the central metal atoms, with angular values in the range between 177.3 (2)° for Mo1—C2≡O2 and 179.2 (3)° for Mo1—C3≡O3. The overall charge of the anionic unit is compensated by two [Cs([2.2.2]crypt)]+ cation complexes. The caesium cations therein are located in the centre of the chelating mol­ecules and are coordinated by two nitro­gen atoms and six oxygen atoms, respectively. The Cs—N and the Cs—O distances in the two cationic units range from 3.053 (2) to 3.107 (3) Å and from 2.9457 (19) to 3.022 (2) Å, and agree with corresponding values in the compound [Cs([2.2.2]crypt)]SCN·H2O (Moras et al., 1973[Moras, D., Metz, B. & Weiss, R. (1973). Acta Cryst. B29, 388-395.]). The positions of the cationic complexes in the crystal structure are determined by weak hydrogen bonds between the donor C—H fragments of the [2.2.2]crypt mol­ecules and the acceptor O atoms of the carbonyl ligands. The shortest distances are found between C32—H32B ⋯ O2 [2.486 (2) Å], C22—H22B⋯O5 [2.663 (3) Å], C21—H21B⋯O1 [2.682 (3) Å] and C16—H16H⋯O2 [2.688 (2) Å] (Fig. 2[link]).

Synthesis and crystallization

Mo(CO)3(η5-Cp)H was prepared via the route documented in the literature (Fischer et al., 1955[Fischer, E. O., Hafner, W. & Stahl, H. O. (1955). Z. Anorg. Allg. Chem. 282, 47-62.]) Cs5Bi4 was prepared by high-temperature synthesis from the elements (Gascoin & Sevov, 2001[Gascoin, F. & Sevov, S. C. (2001). Inorg. Chem. 40, 5177-5181.]). 13 mg (0.05 mmol) Mo(CO)3(η5-Cp)H, 40 mg (0.026 mmol) Cs5Bi4 and 50 mg (0.13 mmol) [2.2.2]crypt were dissolved in dry liquid ammonia in a baked-out reaction vessel. Liquid ammonia was previously dried over sodium metal and condensed using a standard Schlenk line. The mixture was stored at 237 K for crystallization. After several weeks, crystals appeared as red blocks in an orange solution.

Geometry. All esds (except the esd in the dihedral angle between two l.s. planes) are estimated using the full covariance matrix. The cell esds are taken into account individually in the estimation of esds in distances, angles and torsion angles; correlations between esds in cell parameters are only used when they are defined by crystal symmetry. An approximate (isotropic) treatment of cell esds is used for estimating esds involving l.s. planes.

Refinement. All H-atoms could be located from difference Fourier maps, but were positioned with idealized geometry.
