  Three new pseudohalide bridged dinuclear Zn(II), Cd(II) complexes of pyrimidine derived Schiff base ligands: Synthesis, crystal structures and fluorescence studies

  摘要：

  One new dinuclear Zn(II) complex, [(N-3)Zn(L-1)(mu(1,1)-N-3)](2) (1), and a dinuclear Cd(II) complex, [(N-3)Cd(L-1)(mu(1,1)-N-3)](2) (2), of the potentially tridentate NNN-donor Schiff base ligand N-(4,6-dimethylpyrimidin-2-yl)-N'-(1-pyridin-2-yl-ethylidine)-hydrazine (L-1) and another dinuclear Cd(II) complex [(NCS)Cd(L-2)(mu(1,3)-NCS)](2) (3) of a similar NNN donor Schiff base ligand, N-(4,6-dimethyl-pyrimidin-2yl)-N'-pyridin-2-ylmethylene-hydrazine (L-2), have been synthesized and characterized by elemental analyses, IR, H-1 NMR, fluorescence spectroscopy and single crystal X-ray crystallography. The fluorescence spectral changes observed upon addition of the Zn(II) ion to a mixture of L-1 and azide showed high selectivity towards the Zn(II) ion over other metal ions. The ligands L-1 and L-2 are [1 + 1] condensation products of 2-hydrazino-4,6-dimethyl pyrimidine with 2-acetyl pyridine and pyridine-2-carbaldehyde, respectively. In the complexes 1 and 2 the two Zn(II) and Cd(II) centers are held together by mu(1,1)-bridged azide ions, while in 3 the two Cd(II) centers are bridged by mu(1,3)-thiocyanate ions. Complex 1 shows high chelation enhanced fluorescence compared to 2 and 3. All the metal centers have a distorted octahedral geometry. (C) 2011 Elsevier Ltd. All rights reserved.
