Abstract
Crystals of the title compound are orthorhombic, space-group Pna21, with Z= 4, in unit cell of dimensions a= 17·256(15), b= 8·110(10), c= 12·280(13)Å. The intensities of 772 independent reflections above background were collected by counter methods and refined to R 0·077. The titanium atom is in a distorted octahedral environment. The three Ti–Cl bond lengths are significantly different [2·292(7), 2·364(6), and 2·418(7)Å]. The titanium–tertiary nitrogen bond is shorter [2·212(6)Å] than the titanium–pyridine nitrogen bonds [2·269(14) and 2·243(16)Å]. The steric crowding around the metal atom is mainly responsible for the distortions from octahedral symmetry.Keywords
