Crystal structure of cis-aqua­bis­(2,2′-bi­pyridine-κ(2) N,N′)chlorido­chromium(III) tetra­chlorido­zincate determined from synchrotron data

The structure of the title salt, [CrCl(C(10)H(8)N(2))(2)(H(2)O)][ZnCl(4)], has been determined from synchrotron data. The Cr(III) ion is coordinated by four N atoms from two 2,2′-bi­pyridine (bipy) ligands, one O atom from a water mol­ecule and a chloride anion in a cis arrangement, displaying a distorted octa­hedral geometry. The tetra­hedral [ZnCl(4)](2−) anion is slightly distorted owing to its involvement in O—H⋯Cl hydrogen bonding with the coordinating water mol­ecule. The Cr—N(bipy) bond lengths are in the range 2.0485 (13)–2.0632 (12) Å, while the Cr—Cl and Cr—(OH(2)) bond lengths are 2.2732 (6) and 1.9876 (12) Å, respectively. In the crystal, mol­ecules are stacked along the a axis.
