【 摘 要 】

The title molecular structure, namely, diaquatris(μ3-1,3-bis{[1-(2-oxidophenyl)ethylidene]amino}propan-2-olato)-μ3-hydroxido-dinitratohexacopper(II) ethanol trisolvate, [Cu6(C19H19N2O3)3(NO3)2(OH)(H2O)2]·3C2H5OH, corresponds to a non-symmetric hexanuclear copper complex. The complex exhibits one core in which three CuII metal centres are mutually interconnected, two by two, via three phenolato oxygen anions acting in a μ2-mode. These three copper cations are interconnected in a μ3-mode by one hydroxyl group. An open-cube structure is generated in which each of the CuII cations of the three CuO4N units is connected by two μ2-O anions from phenolate groups and one μ3-O atom from a hydroxy anion. Each of the three pentacoordinated CuII cations situated in the open-cube unit has a distorted NO4 square-pyramidal environment. Each of these three CuII centres is interconnected with another CuII cation via one enolate O atom in μ2-mode, yielding one CuNO4 unit and two CuNO3 units. The pentacoordinated CuII atom has a distorted square-pyramidal environment while the two tetracoordinated copper(II) cations are situated in a square-planar environment. A series of intramolecular O—H...O hydrogen bonds are observed. In the crystal, the units are connected two by two by intermolecular C—H...O and O—H...O hydrogen bonds, thus forming sheets parallel to the ac plane.
