Coordination compounds derived from 2,6-diacetylpyridine hydrazones and transition metal ions have yielded a surprisingly rich chemistry. We have favored 2,6-diacetylpyridine bis((iso)nicotinoylhydrazone) for design and synthesis of copper(II) coordination complexes. The interaction in the system CuSO4*5H2O – 2,6-diacetylpyridine bis((iso)nicotinoylhydrazone) give four new binuclear coordination compounds with the compositions: [Cu2(L1)2]·2MeOH·0.5EtOH (1), [Cu2(L1)2]·5.4H2O·1.2EtOH (2), [Cu2(L2)2]·H2O (3) and [Cu2(L2)2]·0.1H2O (4), where H2L1 - 2,6-diacetylpyridine bis(isonicotinoylhydrazone) and H2L2 - 2,6-diacetylpyridine bis(nicotinoyl hydrazone). Crystallographic data for compounds 1-4 are shown in Table. The binuclear molecular complexes [Cu2(L1,2)2] has a similar double helical structure in which two organic double deprotonated anions L1/L2 are coordinated to two metal atoms in a hexadentate mode. Each Cu(II) atom has a octahedron N4O2 coordination surrounding . Compounds 1-4 have been characterized by elemental analysis, IR spectroscopy and single crystal X-ray diffraction method. |
