Abstract
The centrosymmetric title complex, [Ni{S(2)P(OC(2)H(5))(2)}(2)], has been redetermined using area-detector data. The central Ni(S(2)P)(2) core is essentially planar and confirms the early results of McConnell & Kastalsky [Acta Cryst. (1967), 22, 853-859] based on multiple film technique data. In the title structure, the standard uncertainty values are approximately seven times lower and all H-atom positions are calculated. A pair of short symmetry-related H⋯H contacts with distances of 2.33 Å is observed in the crystal structure.
