The title compound, [Ru₂(μ-O₂CCH₃)₄(C₅H₄ClN)₂]PF₆·C₂H₄Cl₂, was obtained via a rapid substitution reaction of 3-chloropyridine for water in [Ru₂(μ-O₂CCH₃)₄(H₂O)₂]PF₆ in 2-propanol and subsequent crystallization from a dichloroethane solution. The cationic diruthenium(II,III) tetraacetate core lies on a crystallographic inversion center with Ru—Ru and Ru—N bond lengths of 2.2738 (3) and 2.2920 (17) Å, respectively. The Ru—Ru—N bond angle is close to linear at 176.48 (4)°, and a significant π-stacking interaction of 3.5649 (16) Å is seen between overlapping pyridine rings of adjacent cations.

Keywords: crystal structure; coordination compound; mixed-valency; diruthenium tetracarboxylate.

Structure description

Earlier research in our lab dealt with the chemistry of various mixed-valent diruthenium(II,III) tetraacetate complexes incorporating substituted pyridines and other, biologically relevant, heterocyclic N-donors in the axial coordination positions (Bland et al., 2005 ; Gilfoy et al., 2001 ; Minaker et al., 2011 ; Vamvounis et al., 2000 ). At that time we were unable to obtain structures of amino- or chloro-pyridine diadducts. Recently, we have been able to characterize both a 3-aminopyridine diadduct (Aquino et al., 2021 ) and the 3-chloropyridine diadduct is reported here. This is the first crystal structure of a chloro-pyridine diadduct of a diruthenium(II,III) tetracarboxylate that we are aware of.

The solvated title salt consists of a complex cation with a diruthenium (II,III) tetraacetate core and 3-chloropyridines in the axial positions, a hexafluoridophophate anion, and a 1,2-dichloroethane molecule of solvation (Fig. 1). The cation displays the classic Chinese lantern or paddlewheel shape with each ruthenium atom at the center of a slightly distorted octahedron. The Ru1—Ru1(−x + 1, −y, −z) and Ru1—N1 bond lengths are 2.2738 (3) and 2.2920 (17) Å, and are similar to those in the 3-cyanopyridine diadduct [2.2702 (6) and 2.295 (3) Å; Minaker et al., 2011]. The Ru1(−x + 1, −y, −z)—Ru1—N1 bond angle of 176.48 (4)° is also comparable to the 174.27 (7)° of the 3-cyanopyridine adduct, showing essentially linear coordination. While no substantial hydrogen bonding was detected in the title compound, a significant π–π stacking interaction between pyridine rings of adjacent complexes was noted (Fig. 2) and creates a chain motif along [010]. The distance between the ring centroids (N1, C1–C5) is 3.5649 (16) Å with a slippage of 0.553 Å, the symmetry code to generate the second ring being (1 − x, 1 − y, −z).

Unlabeled atoms are generated by the symmetry operations (i) (−x + 1, −y, −z) and (ii) (−x + 2, −y, −z + 1). Only one orientation of the disordered methyl groups and the disordered C₂H₄Cl₂ solvent molecule is shown

Synthesis and crystallization

Synthesis of the title compound followed an earlier method developed in our lab (Vamvounis et al., 2000). [Ru₂(μ-O₂CCH₃)₄(H₂O)₂]PF₆ (0.100 g, 0.161 mmol) was dissolved in 10 ml of 2-propanol. Then, 3-chloropyridine (0.0732 g, 0.645 mmol) was added and the solution allowed to stir for 5 min at room temperature. The volume of the solution was then reduced to 5 ml under vacuum and allowed to cool to 278 K overnight. The crystalline product was collected via suction filtration. Yield = 0.098 g (63%). Crystals suitable for X-ray diffraction were obtained by slow diffusion of diethyl ether into a 1,2-dichloroethane solution of the complex. IR (cm⁻¹): 2947 (νC—H), 1447 (asym. νCOO), 1396 (sym. νCOO), 841, (νPF₆), 766 (νC—Cl), 692 (δC—CH₃). UV–vis (λ nm, (log ɛ)): 427 (2.95), 263 (4.05), 210 (4.33).

Refinement

Crystal data, data collection and structure refinement details are summarized in Table 1. Two reflections were removed from the refinement because of poor agreements between F²(obs) and F²(calc), $[\overline{7}]$ $[\overline{7}]$ 5 and $[\overline{8}]$ $[\overline{2}]$ 6. In the cation, the methyl groups of the acetate ligands were modeled in the refinement as idealized disordered methyl groups with the two sets of positions rotated from each other by 60°. The crystal structure was found to contain solvent molecules. The recrystallization solvents were dichloroethane and diethyl ether. The SQUEEZE routine (Spek, 2015 ) in PLATON (Spek, 2020 ) was used to get an estimate of the void volumes and of the unaccounted electron density in them. The unit cell was found to contain one void of 228 Å³ with 50 electrons per void. This suggested that there was one molecule of dichloroethane in each void and it was modeled as such. The disorder in the solvent was modeled by two equally occupied parts, which were then also split again across an inversion center, giving all atoms an occupancy of 0.25. The geometries of all the parts were restrained to be similar. In addition the C—C and the C—Cl bond lengths were restrained to reasonable values. The heavy atoms of the same type in the solvent were restrained to have similar displacement parameters and the carbon atoms were restrained to have more isotropic ellipsoids. Finally, rigid-bond restraints were placed over each solvent part.

Special details top

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.
