Bis(dimethyl sulfoxide-κO)bis(1-phenylbutane-1,3-dionato-κ2O,O′)nickel(II)

Abstract

In the reaction of bis(1-phenyl­butane-1,3-dionato)­nickel(II) with di­methyl sulfoxide, the adduct bis­(di­methyl sulfoxide)­bis(1-phenyl­butane-1,3-dionato)­nickel(II), [Ni(C10H9O2)2(C2H6OS)2], is formed, in which two di­methyl sulfoxide (DMSO) mol­ecules are coordinated to the Ni atom through their O atoms in a trans arrangement. The compound crystallizes in space group P21/a with the Ni atom lying on a center of inversion. The coordination polyhedron around the Ni atom is a distorted octahedron. The chelate ring deviates slightly from planarity. The Ni—O bond distance to the DMSO O atom is slightly longer than that to the 1-phenyl­;butane-1,3-dionate ligand. In the crystal structure, two-dimensional frameworks are formed by C–H⋯O interactions.
