SUPRAMOLECULAR SELF-ORGANIZATION IN CATENA-POLY [DIMETHYL(DIPHENYLPHOSPHINOTHIOATO)THALLIUM(III)], [TLME2(S(O)PPH2)]N, A POLYMER WITH SECONDARY INTERACTIONS BETWEEN THE CHAIN SEGMENTS

The title compound was prepared by the reaction of dimethylthallium(III) hydroxide and diphenylphosphinothioic acid. X-ray diffraction analysis reveals a polymeric structure that can be regarded as a folded ribbon formed by supramolecular association of four-membered TlSOP chelate rings, connected through inter-unit dative O --> Tl bonds [Tl-0 = 2.509(7) angstrom] and Tl ... S secondary interactions [Tl-S = 3.402(3) angstrom]. If all primary and secondary interactions are considered, the thallium atoms are six-coordinate in a severely distorted octahedral geometry.
