The results of the synthesis and spectral (IR) and structural (X-ray diffraction analysis) studies are presented for five binuclear and one tetranuclear copper(II) complexes: [Cu2(H2L1)2](SO4)2 ∙ 4H2O (I), [Cu2(L1)2] · 2MeOH · 0.5EtOH (II), [Cu2(L1)2] · 1.2EtOH · 5.4H2O (III), [Cu2(L2)2] · H2O (IV), [Cu2(L2)2] · 0.1H2O (V), and [Cu4(HL2)4(OH)2](NO3)2 ∙ 6.75H2O (VI), where H2L1 is 2,6-diacetylpyridine bis(isonicotinoylhydrazone) and H2L2 is 2,6-diacetylpyridine bis(nicotinoylhydrazone) (СIF files CCDC nos. 1967853 (I), 1967858 (II), 1967854 (III), 1967855 (IV), 1967856 (V), and 1967857 (VI)). In binuclear complexes I–V with the double spiral structure, both ligands are coordinated via the chelate-bridging mode (3 + 3) to different metal atoms, and the coordination polyhedron of the central atoms (distorted tetragonal bipyramid) is formed by the donor atoms N4O2. In tetranuclear complex cation VI, four copper atoms are joined by four tetradentate monodeprotonated ligands (HL2)– and two bridging ОН– groups. Each metal atom in complex VI is characterized by the tetragonal pyramidal coordination in which the organic ligand is coordinated via the tridentate mode to one metal atom and via the monodentate mode to another atom involving the terminal nitrogen heteroatom (3 + 1). |
