Study of Mixed Amide Coordination Compounds of Copper (II) Nicotinate

Complexes of copper (II) nicotinate with acid amides were synthesized to vary the composition and individual properties compounds obtained through coordination group acetamide, carbamide, thiocarbamide nicotinamide (L1, L2). The organic ligands, environment central ion thermal behaviour elucidated by vibrational spectroscopy analysis. relative intensities spatial structures complexes showed that new differ from each other original components, as they have unique crystal lattices. X-ray diffraction (XRD) analysis was used obtain patterns free molecules nicotinate, compounds. investigated thermolysis products identified. stepwise decomposition found several endo - exo effects correspond constituent parts complexes. Based on intensity electronic spectrum diffuse reflection values bands, six-coordination Cu proven.
