Synthesis and crystal structure of cobalt(II) complex with 2-diphenylacetyl-1,3-indandione

The structure of the synthesized compound of cobalt(II) with 2-diphenylacetyl-1,3-indandione (HL) and two dimethyl sulfoxide molecules was studied by X-ray single-crystal diffraction. One of the dimethyl sulfoxide molecules is disordered over two positions. Crystals of the compound are triclinic: Z = 2, space group P1, a = 11.510(6) Å, b = 11.686(6) Å, c = 16.667(8) Å, α = 93.14(1)°, β = 108.48(1)°, γ = 96.34(1)°. The deprotonated ligand molecules in the inner coordination sphere are located in the equatorial plane of the cobalt coordination polyhedron in the cis configuration. The two DMSO molecules are monodentate coordinated to the central atom through oxygen donor atoms and occupy axial positions.
