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.
