By the reaction of Cu(II) perchlorate with the condensation product of 1,3-diamino-2-propanol and 4-hydroxy-3-formylcoumarin (H3L) in the presence of sodium azide, a tetranuclear copper(II) complex with the composition [Cu2L(μ2-1,1-N3)]2 (I) was obtained. On crystallization from a pyridine solution, the crystalline adduct [Cu2L(μ2-N3)(py)2] (II) (py=pyridine) was obtained and further characterized...
Two novel binuclear heterobridged copper(II) Schiff base complexes of general formula [Cu 2 L(Pz)] (1) and [Cu 2 L(Az)(DMSO)]·DMSO (2) (where L=trianion of bis-azomethine derived from 1-phenyl-3-methyl-4-formylpyrazol-5-one and 1,3-diaminopropan-2-ol, Az=anion of 7-azaindole, Pz=pyrazolate anion) were synthesized and studied by IR spectroscopy and X-ray crystallography. Temperature...
