Abstract

A single thiocyanato bridged 1D polymeric zinc complex with dinuclear asymmetric unit [Zn2L1(mu(1,3)-SCN)(SCH)](n) (1) and a dimeric zinc complex [Zn2L2(NCS)(OOCCH3)(CH3OH)(2)] (2) have been synthesized using two different Schiff bases N,N'-bis(3-methoxysalicylidenimino)-1,3-diaminopropane ((LH2)-H-1) and N,N'-bis(3-ethoxysalicylidenimino)-1,3-diaminopropane ((LH2)-H-2), respectively. All the ligands and the complexes have been characterized by microanalytical and spectroscopic techniques. The structures of the complexes have been conclusively determined by single crystal X-ray diffraction studies. Thermogravimetric analysis has been performed to investigate their thermal stability. Finally, the photoluminescence properties of the complexes as well as their respective ligands have been investigated with a comparative approach. (C) 2013 Elsevier Ltd. All rights reserved.
