[1,2-Bis(diisopropylphosphanyl)ethane-κ²P,P′]dichloridonickel(II)

Abstract

In the crystal structure of title compound, [NiCl2(C14H32P2)], the NiII atom lies on a twofold rotation axis and shows a slightly distorted square-planar coordination geometry, with a dihedral angle of 10.01 (8)° between the cis-Cl—Ni—Cl and cis-P—Ni—P planes. There is no significant inter­molecular inter­action except very weak C—H⋯Cl inter­actions. The crystal studied was a racemic twin.

“…Slightly distorted square-planar coordination geometries are found for complexes 3a , 3b , and 3d , with dihedral angles (φ) between 2.7° and 8.9°. The Ni–P and Ni–Cl bond lengths are very similar for the three complexes and correspond to the values reported for the structurally related complex [(dippe)NiCl 2 ] . As for φ, a subtle influence of the ligand backbone substituent on the bite angles (α) is observed.…”
