Crystal structure of fac-tri-chlorido-[tris-(pyridin-2-yl-N)amine]-chromium(III).

ABSTRACT: In the neutral complex mol-ecule of the title compound, fac-[CrCl3(tpa)] [tpa is tris-(pyridin-2-yl)amine; C15H12N4], the Cr(III) ion is bonded to three N atoms that are constrained to a facial arrangement by the tpa ligand and by three chloride ligands, leading to a distorted octa-hedral coordination sphere. The average Cr-N and Cr-Cl bond lengths are 2.086?(5) and 2.296?(4)?Å, respectively. The complex mol-ecule is located on a mirror plane. In the crystal, a combination of C-H?N and C-H?Cl hydrogen-bonding inter-actions connect the mol-ecules into a three-dimensional network.
