A tetracopper(II) complex containing two μ-oxamidato-dicopper(II) units linked by croconate anions

Abstract

The title compound, di-μ-croconato-bis{μ-[N,N'-bis(3-amino-2,2-dimethylpropyl)oxamidato(2-)-N,O':N',O]-dicopper(II)} tetrahydrate, [Cu 4 (C 12 H 24 N 4 O 2 ) 2 (C 5 O 5 ) 2 ].4H 2 O, comprises two μ-oxamidato-dicopper(II) units bridged by croconate ligands to give a tetracopper(II) ring system with crystallographic 1 symmetry; all the copper centres are five-coordinate.
