Cu2+-Induced formation of cage-like compounds containing pyrazole macrocycles

The crystal structure of the complex [Cu4(H22L)2(H2O)2- (ClO4)2](ClO4)2·2H2O where L is a new pyrazole ligand containing 1,5-diaminopentane spacers represents a new form of obtaining metal ion-induced inorganic–organic cages.Escarti Alemany, Francisco, franesa@alumni.uv.es ; Latorre Saborit, Julio, Julio.Latorre@uv.es ; Garcia-España Monsonis, Enrique, Enrique.Garcia-Es@uv.e
