Syntheses, Crystal Structures and Thermal Decomposition Kinetics of Ni(II) and Cu(II) Complexes with dpa and dca: [Ni(dpa)_2(clca)_2] and [Cu(dpa)_2(dca)_2] (dpa = 2,1'-Dipyridylamine, dca = Sodium Dicyanamide) Ligands

摘要

The syntheses, crystal structures, luminescence properties and thermal decomposition kinetics of Ni(II) and Cu(H) complexes with dpa and dca, [Ni(dpa)_2 (dca)_2] (I) and [Cu(dpa)_2(dca)_2] (II) (dpa = 2, 2'-dipyridylamine, dca = sodium dicyanamide) are described. I crystallizes in Monoclinic cells with c2c space groups; the center metal ion Ni~(II) lies in a distorted octahedron environment, and the endmost nitrogen atom of dca with a "V" model coordinates to Ni~(II). Though the chemical formula of II is similar to I, II crystallizes in triclinic cells with a Pi space group. The center Cu~(II) Ion has an octahedral-coordinated environment.
