Popis:	The crystal structure of a binuclear CuII complex which contains both µ phenoxo and µ-hydroxo bridging groups as well as two terminal piperazine N and one water O atoms on each Cu shows a very short Cu–Cu distance [2.872(2)A] and an unusual pyramidal geometry around the phenoxo O atom; this complex is unusual in that no net antiferromagnetic coupling is evident and reasons are put forward to explain this reduced coupling.
