Structure of Pimethixene Maleate

Abstract

The crystal of the title compound, C₁₉H₁₉NS·C₄H₄O₄, belongs to space group Pbca with cell dimensions of a = 17.0132(4), b = 9.3344(2), c = 26.1413(4)Å. The final R value is 0.073. The thioxanthene ring takes a butterfly conformation with the dihedral angle between the two phenyl rings being 50.4(1)°. The piperidine ring takes a slightly deformed-chair conformation.
