Three different types of copper(II) complexes have been studied of the hexadentate Schiff base ligand N,N'-bis[2-{(salicylidenimine)amino}ethyl] piperazine (H2L) having the piperazine backbone in the chair form and axial-axial (a,a) N-atom lone pairs in the free state. The structure of the products is influenced by the reaction conditions and by the exogenous ligands, affecting the conformation of the piperazine moiety (primary structure) and the topology and nuclearity of the resulting… Expand
