Bis[trans-di­fluorido­tetra­kis­(pyridine-κN)chromium(III)] sodium tetra­chlorido­zincate perchlorate from synchrotron data

The title salt, Na[CrF(2)(C(5)H(5)N)(4)](2)[ZnCl(4)]ClO(4), consists of two cationic Cr(III) complexes, an Na(+) cation, one [ZnCl(4)](2−) anion and one ClO(4) (−) anion. The Cr(III) atoms are coordinated by four pyridine (py) N atoms and two F atoms in a trans arrangement, displaying a distorted octa­hedral geometry. The mean Cr—N(py) and Cr—F bond lengths are 2.086 (8) and 1.864 (14) Å, respectively. The [ZnCl(4)](2−) anion has a distorted tetra­hedral geometry. The most notable feature of the crystal packing is the formation of weak pyridine–perchlorate C—H⋯O hydrogen bonds, resulting in supra­molecular chains along the b-axis direction. The perchlorate anion was disordered over two sets of sites in a 0.868 (3):0.132 (3) ratio.
