The simultaneous presence of different varieties of intermolecular hydrogen bonds in a new layer-type anionic host lattice built of thiourea, fumaric acid and fumarate anion

摘要

A new inclusion complex (n-C4H9) N-4(+) C4H3O4- center dot C4H4O4 center dot ( NH2)(2)CS has been prepared and characterized by X-ray crystallography. Crystal data: space group P (1) over bar, a = 8.799( 2) angstrom, b = 9.590( 1) angstrom, c = 18.684( 4) angstrom, alpha = 89.63( 1)degrees, beta = 79.56( 1)degrees, gamma = 79.74( 1) degrees, V = 1525.2( 5) angstrom(3), Z = 2, R-1 = 0.0562 and wR = 0.1033. In the title compound, thiourea molecules, fumaric acid and fumarate anions are joined together by typical O - H center dot center dot center dot O, N - H center dot center dot center dot O and N - H center dot center dot center dot S, plus weak C - H center dot center dot center dot O and C - H center dot center dot center dot S, hydrogen bonds to generate a hydrogen-bonded layer corresponding to the ( 100) family of planes. The tetra-n-butylammonium cations are orderly arranged in a sandwich-like packing mode between the stacked layers. The simultaneous presence of different varieties of intermolecular hydrogen bonds is an interesting feature of the title compound.
