The crystal structure of Tetraisothiocyanatotetrakis(tetramethylurea)thorium(IV)

Abstract

The structure of the title complex has been determined by single- crystal X-ray crystallography. The crystals are monoclinic, a 13.954(1), b 20.334(2), c 14.138(1) Ǻ, β 98.06(3)°, space group P2₁/c. The structure was refined to a residual of 0.044 by using 3875 structure amplitudes. The molecules are eight-coordinate, the coordination polyhedron being a slightly distorted dodecahedron with the oxygen and nitrogen donor atoms equally distributed between the A and B sites.
