Abstract
The structure of S,S'-(1,8-octanediyl)bis(thiouronium) tetrachloroplat inate(II), [C10H24N4S2]-[PtCl4], consists of square-planar PtCl42- ani ons and BTUO2+ cations [where BTUO2+ is the bis-protonated form of the organic ligand 1,8-octanediylbis(thiourea)]. This cation exhibits a c entre of symmetry and packs in a mixed trans (t) and gauche (g) config uration, with a tgtttttgt zigzag sequence which is in contrast to the extended all-trans configuration observed in the homologous copper(II) compound [BTUO][CuCl4]. The C(3) and C(4) atoms of the alkyl chain sh ow statistical disorder. The BTUO2+ cations are sandwiched between mon omeric planar ptCl42- layers.
