Abstract
A cubane-type core has been found in the tetrameric title complex, aqua-1κC-tetrakis(4-chlorobenzoato)-1κC,2κC,3κC,4κC-tetrakis[μ 3 -(2-dimethylaminoethanolato)-κ 3 O:O:O]-tetrahedro-tetracopper(II) hydrate, [Cu 4 (C 7 H 4 ClO 2 ) 4 (C 4 H 10 NO) 4 (H 2 O)].H 2 O. The structure of the complex molecule is composed of two ethanolate O-bridged dimers, with Cu-O bond lengths in the range 1.919 (5)-1.979 (5) A, and Cu…Cu distances of 2.855(2) and 2.890(2)A. The dimers are bridged into the tetrameric unit by triply bridging ethanolate O atoms, with Cu-O distances in the range 2.417 (5)-2.618 (5) A. Of the four Cu atoms, three are five-coordinated and one is six-coordinated.
