title: Crystal structure of cis-aqua-bis-(2,2'-bi-pyridine-κ(2) N,N')chlorido-chromium(III) tetra-chlorido-zincate determined from synchrotron data.
abstract: The structure of the title salt, [CrCl(C10H8N2)2(H2O)][ZnCl4], has been determined from synchrotron data. The Cr(III) ion is coordinated by four N atoms from two 2,2'-bi-pyridine (bipy) ligands, one O atom from a water mol-ecule and a chloride anion in a cis arrangement, displaying a distorted octa-hedral geometry. The tetra-hedral [ZnCl4](2-) anion is slightly distorted owing to its involvement in O-H⋯Cl hydrogen bonding with the coordinating water mol-ecule. The Cr-N(bipy) bond lengths are in the range 2.0485 (13)-2.0632 (12) Å, while the Cr-Cl and Cr-(OH2) bond lengths are 2.2732 (6) and 1.9876 (12) Å, respectively. In the crystal, mol-ecules are stacked along the a axis.
