摘要：

The complexes [M(2,4'-bpyMe)X3] . nH2O (M = Pd, Pt; X = Cl, Br; 2,4'-bpyMe = 1-methyl-2,4'-bipyridinium, n = 0, 1, 2) cyclometallate with elimination of HX to give [M(2,4'bpyMe-H)X2] in the solid state on heating or upon microwave irradiation. Thermal analysis (TGA, DTA, DSC) in conjunction with infrared spectroscopy indicates that these complexes cyclometallate in the temperature range 160-260-degrees-C. The ease of cyclometallation is Pd > Pt and Cl > Br. The time of cyclometallation with microwave irradiation depends on the mode of irradiation.
