Three new mononuclear complexes of copper(II), viz. [Cu(L)(N3)Cl] (1), [Cu(L0)(H2O)]ClO4 (2) and [Cu(L00)](3) where L = N-(3-aminopropyl)-N-methylpropane-1,3-diamine, L0 = 2-(N-{3-[(3-aminopropyl)(methyl)amino]propyl}ethanimidoyl)phenolate ion and L00 = 2,20-{(methylimino)bis[propane-3,1-diylnitrilo(1E)eth-1-yl-1-ylidene]}diphenolate ion, have been prepared. The synthesis of complex 1 has beenachieved by reacting copper chloride with the triamine (L) and sodium azide in a 1:1:1 M ratio. The othertwo compounds have been synthesized by the reaction of copper perchlorate with the same triamine, L,plus 2-hydroxyacetophenone in a molar ratio of 1:1:1 (for 2) and 1:1:2 (for 3), so that the respective tetradentateand pentadentate Schiff bases HL0 and H2L00 are formed in situ to bind the copper(II) ions. Thecomplexes have been characterized by microanalytical, spectroscopic and single crystal X-ray diffractionstudies. Structural studies reveal that the mononuclear units of all the three complexes adopt a distortedsquare pyramidal geometry and are held together by either intermolecular H-bonding (in 1 and 2) or C-H..p interactions (in 3) to form supramolecular networks in the solid state.
