Crystalline O,O′-di-sec-butyl and O,O′-diethyl dithiophosphate platinum(II) complexes: Synthesis, 13C and 31P CP/MAS NMR, single crystal X-ray diffraction studies and thermal behaviour

► The molecular structure of bis(O,O′-di-sec-butyldithiophosphato-S,S′)platinum(II). ► Four-membered chelate rings [PtS2P] and the planar [PtS4] chromophore. ► 13C, 31P MAS NMR parameters and thermal behaviour of platinum(II) dithiophosphates. ► Thermal destruction of the complex yields intermediate [Pt(S2PO)2] and metallic Pt.
