摘要: Abstract The synthesis, IR-spectra and thermal analysis of tetrahedral or octahedral Cd(II)-complexes 3(5)-amino-5(3)-methylpyrazole (L), as represented by the general formula CdX 2 L · n H O ( X = NCS − , NCO Cl =2; 1/2 SO 2− 4 =1), complex Cd(OAc) 3 ·H are described. Thermal decomposition acetato results in an intermediate, appearing 480–580 K range. On basis IR-spectrum elemental a scheme is proposed. Because involvement different anion, other complexes differs from that complex.
