Abstract
A thermal study (simultaneous TG and DTA measurements) was carried out on the dithiocarbazic ester complexes M[N3CH2R1N2C1(S)SCH3]2, where M=Ni, Pt; R1=C6H5. The following disproportionation reaction occurs in the solid state: II is formed through deprotonation of the CH2 group bound to N3, whereas III is formed through protonation of N3.The influence of inductive and/or steric effects on the mechanism of this reaction is discussed, taking into account the electrochemical and X-ray data on the complexes Pt[NRNC(S)SR']2 with differentR substituents: R=H, Ph, CH2Ph, CH2C5H11, CH(CH3)2, C(CH3)3; R′=CH3, CH2Ph.These results accord with the behaviour of the same complexes in solution.
