Structural and magnetic studies of a syn-anti carboxylate-bridged helix-like chain copper(II) complex

摘要: The preparation, magnetic properties, and crystal molecular structure of [CuL(H 2 O)] n are described (L stands for the doubly deprotonated form 1,3-dimethyl-5-((2-carboxyphenyl)azo)barbituric acid). crystals orthorhombic, space group P2 1 121 , with cell constants a=8.171 (1) A, b=10.302 (3) c=17.006 (5) Z=4. was solved refined to R=0.052. copper(II) ions in a distorted square-pyramidal environment
