Dichloridotris(trimethyl-phosphine)nickel(II)

Abstract

The title compound, [NiCl2(C3H9P)3], was obtained as a product of the reaction of [NiCl2(PMe3)2] with an equivalent trimethyl-phosphine in diethyl ether. It easily loses trimethyl-phosphine at room temperature to give NiCl2(PMe3)2. There are two independent mol-ecules in the asymmetric unit, and their bond lengths and angles are similar. The Ni environment is trigonal bipyramidal. One Ni, one P and two Cl atoms lie in the equatorial plane, with the remaining two P atoms occupying axial positions. The equatorial Ni - P bond length is shorter than the axial bond lengths. © 2008 International Union of Crystallography.
