A new pyrazole-based ligand, namely 1,3-bis(3,5-dimethylpyrazol-1-yl)-2-butanoic acid (Hbdmpb) was synthesised together with its copper complex Na[Cu(bdmpb) 2 (OOCCH 3 )H 2 O]·4H 2 O. Both the free ligand and its Cu compound were fully characterised and their crystal structures were determined by X-ray analysis. The free-ligand molecular structure is uneventful. The...
Reaction of a simple Schiff-base ligand bis(hydroxylbenzyl)diaminoxylene (H 2 -p-xysal) with copper(II) perchlorate results in the formation of Cu 2 (p-xysal) 2 with a double-stranded helicate structure, constructed from two slightly different units of dinuclear Cu(II), in which all the copper(II) ions have distorted tetrahedral geometries. The two sublattices are interpenetrating...
