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

In the neutral complex mol­ecule of the title compound, fac-[CrCl(3)(tpa)] [tpa is tris­(pyridin-2-yl)amine; C(15)H(12)N(4)], 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 octa­hedral co...

Sumario:In the neutral complex mol­ecule of the title compound, fac-[CrCl(3)(tpa)] [tpa is tris­(pyridin-2-yl)amine; C(15)H(12)N(4)], 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 octa­hedral coordination sphere. The average Cr—N and Cr—Cl bond lengths are 2.086 (5) and 2.296 (4) Å, respectively. The complex mol­ecule is located on a mirror plane. In the crystal, a combination of C—H⋯N and C—H⋯Cl hydrogen-bonding inter­actions connect the mol­ecules into a three-dimensional network.
