Abstract

Two Zinc(II) and Cadmium(II) coordination polymers, namely [ZnCl2(µ-ptmb)]n (1) and [Cd(µ4-SO4)(µ-ptmb)]n (2) have been obtained with hydrothermal method at 120°C based on flexible ligand 1,4-bis((1H-1,2,4-triazol-1-yl)methyl)benzene (ptmb) in this study. The single-crystal X-ray analyses indicate that complexes 1 and 2 crystallize in the triclinic with P-1 space group and the orthorhombic crystal system with space group Pccn, respectively. In 1, Zn(II) ions display a tetrahedral geometry with two chloride and two ptmb ligands. The ptmb ligand acts to bridge neighboring Zn(II) centres into a 1D zig-zag polymeric chain structures. In 2, Cd(II) ions display octahedral geometry with two ptmb and four different sulfato ligands. Four contiguous Cd(II) ions are bridged through the agency of four sulfato ligands to form a 2D layer. Two adjacent 2D layers further extended into a 3D structure through the bridging ptmb ligands. Besides, the thermal properties of synthesized new complexes have been investigated.

Özet

Bu çalışmada esnek 1,4-bis((1H-1,2,4-triazol-1-yl)metil)benzen (ptmb) ligandı esas alınarak 120°C de hidrotermal sentez yöntemiyle [ZnCl2(µ-ptmb)]n (1) ve [Cd(µ4-SO4)(µ-ptmb)]n (2) kapalı formülüne sahip iki yeni Çinko(II) ve Kadmiyum(II) koordinasyon polimeri sentezlenmiştir. X-ışınları tek kristal analiz sonuçlarına göre 1 ve 2 kompleksi sırasıyla P-1 uzay grubu ile triklinik ve Pccn uzay grubu ile ortorombik kristal sisteminde kristallenmişlerdir. 1 de Zn(II) iyonları iki ptmb ligandı ve iki klor ile tetrahedral geometri göstermiştir. Ptmb ligandı komşu Zn(II) merkezleri arasında köprü rolü oynayarak 1D zig-zag polimerik zincir yapılar oluşturmuştur. 2, de Cd(II) iyonları iki ptmb ve dört farklı sülfat ligandı ile oktahedral geometri sergilemiştir. Dört bitişik Cd(II) iyonları 2D tabaka oluşturmak için dört sülfat ligandı ile köprülenmiştir. 2D tabakalar köprü ptmb ligandı sayesinde 3D kafes yapıya genişler. Ayrıca, yeni komplekslerin termal özellikleri incelenmiştir.
