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.
