Microcalorimetric measurements at elevated temperatures of the enthalpies of thermal decomposition of selected cis-[PtL2X2] complexes (L = NH3, amines, or pyridine; X = Cl, Br, or I) have been used to derive the standard enthalpies of formation, ΔHf⊖(c)/kJ mol–1, of the following crystalline compounds: [Pt(NH3)2Cl2]=–(467 ± 3); [Pt(NH3)2Br2]–(404 ± 7); [Pt(NH3)2l2]=–(295 ± 6); [Pt(NH2Me)2C12]=–(424
