Abstract
The complexes [NiL3](NO2)2•2H2O (violet, 1) and cis-[NiL2 (NO2)2]•0.5H2O (pink, 1b) (L=1,2-diamino-2-methylpropane) have been synthesized from solution. The X-ray single crystal structure analysis of compound 1b has been carried out, but the presence of a water molecule cannot be detected. Upon heating, complex 1b undergoes dehydration followed by an endothermic phase transition to produce trans-[NiL2 (NO2)2] (1d). The violet species (1) also undergoes dehydration upon heating with deamination resulting (1d).
