trans-Difluoridotetrakis(pyridine-κN)chromium(III) perchlorate from synchrotron radiation

چکیده
The are two independent complex cations in the title salt, [CrF2(C5H5N)4]ClO4, each located on a centre of inversion, as well as an independent perchlorate counter-ion. The complex cations adopt slightly distorted octa-hedral coordination environments around the Cr(III) ion, defined by four pyridine (py) N atoms in the equatorial plane and two F(-) ligands in the axial positions; intra-molecular C-H⋯F contacts are noted. The mean Cr-N(py) and Cr-F bond lengths are 2.088 (6) and 1.8559 (10) Å, respectively. The three-dimensional architecture is sustained by hydrogen bonds involving the pyridine C-H groups as donors, and F and O atoms as acceptors.
