Abstract: In the title crystal structure, [Ni₂Cl₄{CH₂(CH₂CH₂PPrⁱ₂)₂}₂], there are two independent molecules, one of which lies on a crystallographic inversion center. The Ni^II atoms in each dinuclear molecule are in slightly distorted square-planar geometries. The two independent molecules have markedly different conformations due to the relative orientations of the Cl/Ni/Cl groups with respect to the plane defined by the four P and the two Ni^II atoms.
