In the title solvated complex salt, [Cu(C27H39BN6S3)(C2H5NO)](CF3O3S)·2CHCl3, the CuI atom is coordinated by the three S atoms of the pyridazine-3-thione rings in the equatorial plane [Cu—S = 2.3072 (4)–2.3280 (4) Å] and the B atom of the scorpionate ligand and the O atom of an acetamide ligand as the apices of a trigonal bipyramid [Cu—B = 2.0456 (16) Å and Cu—O = 1.9957 (11) Å]. The amide group of the latter ligand is involved in a bifurcated hydrogen bond to the trifluoromethanesulfonate anion.
Keywords: crystal structure; copper; trigonal–bipyramidal coordination; scorpionate; boratrane.

Structure description
Since the first description of a metallaboratrane complex (Hill et al., 1999), this class of compounds has been used extensively in coordination chemistry (Amgoune & Bourissou, 2011; Bouhadir & Bourissou, 2016). Their Z-type coordination mode provides an entry into electronically interesting metal atoms, which recently were successfully used in catalytic dinitrogen reduction (Anderson et al., 2013). Our group is focusing on thiopyridazine-based soft scorpionates and their related metallaboratrane complexes (Nuss et al., 2011a,b; Holler et al., 2016, 2017). In an attempted synthesis of the boratrane complex {2,2′,2′′-boranetriyltris[6-tert-butyl-4-methylpyridazine-3(2H)-thione]}(trifluoromethanesulfonato)copper(I) (= [Cu{B(PnMe,tBu)3}(OTf)]), described in the literature by our group (Holler et al., 2016), the title compound formed serendipitously by reaction with residual acetamide from the acetonitrile solvent.
As in the boratrane complexes [Cu{B(PnMe,tBu)3}X] (X = Cl, OTf, N3, NCS) the CuI atom in the title compound (Fig. 1) has a slightly distorted trigonal–bipyramidal environment (Table 1) with a rather short Cu—B distance comparable to 2.0432 (14) Å observed in the trifluoromethanesulfonate complex (Holler et al., 2016). Not the trifluoromethanesulfonate anion but the neutral acetamide molecule [Cu1—O1 1.9957 (11) Å] occupies the axial position opposite to the B atom. In the other boratrane complexes [Cu{B(PnMe,tBu)3}X] with more polarizing ligands, the Cu—B distance is distinctly longer [e.g. 2.065 (2) Å for X = Cl, 2.068 (4) Å for X = N3, 2.0667 (13) Å for X = NCS]. One H atom of the NH2 group shows a bifurcated hydrogen bond (Table 2) to the trifluoromethanesulfonate anion (Fig. 1), the other one is not able to build a hydrogen bond. A non-classical hydrogen-bonding interaction can be assumed between C5 of a chloroform solvent molecule and the trifluoromethanesulfonate anion (Table 2).

Synthesis and crystallization
During an attempted synthesis of [Cu{B(PnMe,tBu)3}(OTf)] (Holler et al., 2016), the title compound crystallized due to residual acetamide in the used acetonitrile solvent. AgOTf (21.4 mg, 0.083 mmol) and [Cu{B(PnMe,tBu)3}Cl] (54.4 mg, 0.083 mmol) were suspended in anhydrous acetonitrile (4 ml). The reaction mixture was stirred at room temperature for 90 min, the resulting suspension was centrifuged and filtered. The solvent was removed in vacuo to obtain an orange solid. Crystals suitable for X-ray were obtained by slow evaporation of a CDCl3 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. Refinement of F2 against ALL reflections. The weighted R-factor wR and goodness of fit S are based on F2, conventional R-factors R are based on F, with F set to zero for negative F2. The threshold expression of F2 > 2sigma(F2) is used only for calculating R-factors(gt) etc. and is not relevant to the choice of reflections for refinement. R-factors based on F2 are statistically about twice as large as those based on F, and R- factors based on ALL data will be even larger. The non-hydrogen atoms were refined with anisotropic displacement parameters without any constraints. The positions of the H atoms of the NH2 group were taken from a difference Fourier map, the N-H distances were fixed to 0.88 Å, and the H atoms were refined with common isotropic displacement parameters without any constraints to the bond angles (DFIX of SHELXL). The H atoms of the tertiary C-H groups were refined with individual isotropic displacement parameter and all Cl-C-H angles equal at a C-H distance of 1.00 Å (AFIX 13 of SHELXL). The H atoms of the pyridazine rings were put at the external bisectors of the C-C-C angles at C-H distances of 0.95 Å and common isotropic displacement parameters were refined for the H atoms of the same phenyl group (AFIX 43 of SHELXL). The H atoms of the methyl group C2 are disordered over two orientations and were refined with site occupation factors of 0.5 at two positions rotated from each other by 60 ° with common isotropic displacement parameters for the H atoms and idealized geometry with tetrahedral angles, enabling rotation around the C-C bond, and C-H distances of 0.98 Å (AFIX 127 of SHELXL). The H atoms of the other methyl groups were refined with common isotropic displacement parameters for the H atoms of the same group and idealized geometries with tetrahedral angles, enabling rotation around the C-C bond, and C-H distances of 0.98 Å (AFIX 137 of SHELXL). |
