Bis(dimethyl sulfoxide-kappa O)bis(1-phenylbutane-1, 3-dionato-kappa O-2, O ')nickel(II)

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-HO interactions.
