THERMAL-PROPERTIES OF COMPLEXES M(NH3)2[AG(CN)2]2 (M(II) = NI, CU, CD)

Complexes of composition M(NH3)2[Ag(CN)2]2, where M = Ni (NiA), Cu (Cu A), Cd (CdA), have been prepared and identified by infrared and electr on spectroscopy and by magnetic susceptibility measurements. Thermal s tability and stoichiometry of thermal decomposition were investigated by using a derivatograph. The intermediates of thermal decomposition w ere identified by IR spectroscopy and X-ray powder diffraction. The re sults showed that the thermal stability increased in the order CuA, Cd A, NiA.
