摘要:
Complexes of Cu(Il) and Co(II) nitrates with 3-phenyl-5,5-dimethyl-5,6-dihydro-1,2,4-triazolo[3,4-alisoquinoline (L-0) of the composition [CuL20 (NO3)(2)] (I) and [CoL20(NO3)(2)] center dot CH3CN are synthesized and their crystal structures are determined by X-ray diffraction. The L-0 ligand is coordinated to the metal atoms through the N atom in position 2 of triazole fragment. The coordination polyhedron of the Cu(II) atom is a square with two additional axial vertices, while that of the Co(II) atom is a tetrahedron with two additional vertices. The NO3- groups in the structures of I and II perform similar anisobidentate function. Complexes I and II are studied by IR and electronic spectroscopy.
