Özet
Four novel coordination polymers, namely [Co(mu(3)-tdp)(ina)(2)](n) (1), [Cu(mu(3)-tdp)(ina)(2)](n) (2), [Zn(mu(3)-tdp)(ina)(2)] (3) and [Zn(mu(3)-tdp)(na)2](n) (4) [tdp: 3,3'-thiodipropionate, ma: isonicotinamide and na: nicotinamide], were synthesized and structurally characterized by elemental analysis, IR and single-crystal X-ray diffraction techniques. Each M(II) ion (M(II)=Co(II) in I, Cu(II) in 2, Zn(II) in 3 and Zn(II) in 4) is coordinated by two nitrogen atoms of two different pyridine rings and four oxygen atoms from three different tdp ligands, forming distorted octahedral geometries. The tdp ligand exhibits an unprecedented coordination mode, namely the mu(3)-kappa O,O':kappa O:kappa O-bridging mode. Single crystal X-ray diffraction analysis results demonstrated that complexes 1-4 exhibit 2D layers with a point symbol of 3(3)center dot 4(3)center dot 5(4), which are extended into 3D supramolecular frameworks by R-2(2)(8) hydrogen-bonding motifs. Thermal analysis results showed that 2D complexes are stable up to 225, 189, 196 and 162 C, respectively. Moreover, the photoluminescent properties of complexes 3 and 4 were investigated at room temperature. (C) 2013 Elsevier Ltd. All rights reserved.
