Abstract

Four different limiting molecular conformations are possible for the homoleptic square-planar complex tetrakis (thiourea) platinum(II) depending on the up-down orientation of the four thiourea (TU) ligands with respect to the PtS4 plane. The realization of all four possible conformers can be achieved by a systematic variation of the counter anion making use of their individual hydrogen bonding ability. In total, the molecular and crystal structures of seven tetrakis (thiourea) platinum(II) complexes were determined by X-ray diffraction. These are: [Pt(TU)(4)]Cl-2, [Pt(TU)(4)]I-2, [Pt(TU)(4)](CF3SO3)(2), [Pt(TU)(4)](BPh4)(2), [Pt(TU)(4)](CIO4)(2), [Pt(TU)(4)]SiF(6)(.)0.25H(2)O and [Pt(TU)(4)]S2O6. In all cases thiourea is coordinated by the sulfur atom and the two amino groups are not involved in the complex formation. The four independent Pt-S distances do not differ significantly from each other with an average value of 2.324(3) angstrom. The coordination geometry around the platinum center is distorted square-planar. The orientation of the four TU groups in [Pt(TU)(4)](2+) depends on the molecular packing forces and hydrogen bonding ability of the counter aO0 and S) are observed. (c) Wiley-VCH Verlag GmbH & Co.
