Abstract

The reaction of imidazole (Him) with $[Cu_2(\mu-O_2CMe)_4(H_2O)_2]$ in water-$NaClO_4$ led to the formation of a polynuclear copper(II) complex, $[Cu_5(OH)_2(H_2O)(O_2CMe)_6(Him)_4][ClO_4]_21$, in which the pentanuclear units, showing four, five and six co-ordination geometries for the copper(II) centres and Cu...Cu distances of 3.043(1), 3.178(1) and 3.578(1)$\AA$, were linked by aqua bridges to give an intra-chain inter-unit Cu...Cu separation of 4.507(1)$\AA$.
