Crystal structure of trans-di-fluoridotetra-kis(pyridine-κN)chromium(III) tri-chlorido-(pyridine-κN)zincate monohydrate from synchrotron data.

ABSTRACT: In the asymmetric unit of the title compound, [CrF2(C5H5N)4][ZnCl3(C5H5N)]·H2O, there are two independent complex cations, one tri-chlorido-(pyridine-κN)zincate anion and one solvent water mol-ecule. The cations lie on inversion centers. The Cr(III) ions are coordinated by four pyridine (py) N atoms in the equatorial plane and two F atoms in a trans axial arrangement, displaying a slightly distorted octa-hedral geometry. The Cr-N(py) bond lengths are in the range 2.0873 (14) to 2.0926 (17) Å while the Cr-F bond lengths are 1.8609 (10) and 1.8645 (10) Å. The [ZnCl3(C5H5N)](-) anion has a distorted tetra-hedral geometry. The Cl atoms of the anion were refined as disordered over two sets of sites in a 0.631 (9):0.369 (9) ratio. In the crystal, two anions and two water mol-ecules are linked vi
