Crystal structure of cis-aqua­chlorido­bis­(1,10-phenanthroline-κ(2) N,N′)chromium(III) tetra­chlorido­zincate monohydrate from synchrotron data

The structure of the title compound, [CrCl(C(12)H(8)N(2))(2)(H(2)O)][ZnCl(4)]·H(2)O, has been determined from synchrotron data. The Cr(III) ion is bonded to four N atoms from two 1,10-phenanthroline (phen) ligands, one water mol­ecule and a Cl atom in a cis arrangement, displaying an overall distorted octa­hedral coordination environment. The Cr—N(phen) bond lengths are in the range of 2.0495 (18) to 2.0831 (18) Å, while the Cr—Cl and Cr—(OH(2)) bond lengths are 2.2734 (7) and 1.9986 (17) Å, respectively. The tetra­hedral [ZnCl(4)](2−) anion is slightly distorted owing to its involvement in O—H⋯Cl hydrogen bonding with coordinating and non-coordinating water mol­ecules. The two types of water mol­ecules also inter­act through O—H⋯O hydrogen bonds. The observed hydrogen-bonding pattern leads to the formation of a three-dimensional network structure.
