摘要:
The crystal and molecular structure of [Cu-2(CH3COO)(4)(Hbet)(2)] (Hbet = betaine: N,N,N-trimethylglycine: trimethylammonioacetate) was determined by a single-crystal X-ray diffraction method. The complex has a water-wheel-like structure which appears in [Cu-2(CH3COO)(4)(H2O)(2)]; the carboxylato oxygen atom of Hbet is coordinated to a copper atom instead of to a water molecule. The magnetic moment of this complex is 1.46 BM, which suggests the existence of an interaction between copper atoms. (C) 1999 Elsevier Science S.A. All rights reserved.
