摘要：

Thermal reactions of [Ni(diamine)2(H2O)2](NO3)2 and [Ni(diamine)2(NO3)2] (where diamine = 1,2-ethanediamine, N-methyl-1,2-ethanediamine, N-ethyl-1,2-ethanediamine, 1,3-propanediamine and N-methyl-1,3-propanediamine) have been investigated in the solid phase. The 1,2-ethanediamine and N-methyl-1,2-ethanediamine complexes undergo thermally induced endothermic irreversible isomeric transformations. In the 1,2-ethanediamine complex the transformation is thermochromic, whereas it is not for the N-methyl-1,2-ethanediamine complex. The transformations are explained in terms of the axial interaction of NO3 ions with nickel as well as to ligand field weakening resulting from conformational changes of the individual diamine chelate rings.
