  Sodium ion assisted molecular self-assembly in a class of Schiff-base copper(II) complexes

  摘要：

  Syntheses, characterization and crystal structures of three new sodium based heterotrinuclear ionic clusters [(CuL1)(2)Na(ClO4-O,O')(OH2)]center dot C8H8O2 (1), [(CuL2)(2)Na(ClO4-O,O')] (2) and [(Cu(L-3)(2))(2)Na](+)center dot ClO4- (3) derived from three different Schiff bases (L1 = 1:2 condensation of 1,2-propane diamine and o-hydroxy acetophenone, L2 = 1:2 condensation of 1,2-propane diamine and 2-hydroxy-5-methoxy acetophenone and L3 = 1:1 condensation of 2-amino pyridine and 3-ethoxy salicylaldehyde) are reported herein. The crystal structure analysis reveals that the square-planar Cu-ligand complexes act as building block for the trinuclear complex in which Na+ ion guides the orientation of Cu(II) Schiff-base complexes into a scissor like architecture in 1 and 2. The unique assembling feature of Na* ion is also evident in complex 3 where even in the presence of a widely different Schiff-base ligand, Na+ guides two Cu(II)(L3)2 complexes to assemble around it in a crown ether like environment. In complexes 1 and 2 the square planar metal coordination provide suitable sites for chelate ring pi center dot center dot center dot pi interaction and Cu center dot center dot center dot pi interaction which ensures columnar assembly of trinuclear units at the supramolecular level. The present study reveals the unique nature of the self-assembly of square-planar Cu(II) Schiff-base complexes around Na+. (C) 2012 Elsevier Ltd. All rights reserved.
