Popis: A novel coordination polymer, [Cd2(PMP)2Cl4] n (PMP = 1-phenyl-3-methyl-2-pyrazoline-5-one), was prepared by the reaction of cadmium chloride hemidihydrate and PMP, and characterized by elemental analysis, IR spectrum, TGA/DTA and electrochemical analysis. Single crystal X-ray diffraction revealed that the title complex is orthorhombic, space group Pna2(1), with a = 16.5398(14), b = 18.238(2), c = 3.8367(7) A, V = 1157.4(3) A3, Z = 2. Each cadmium atom is hexa-coordinate and surrounded by an OCl5 environment, adopting a distorted octahedral geometry, in which three Cl− ions act as μ3-linker and two as μ2-linker. The Cd(II), Cl− and PMP form an infinite 1D chain with complicated chair-like features through μ2- and μ3-Cl bridges. The electrochemical behavior of the complex was investigated in DMF by cyclic voltammetry. The antibacterial activity of the complex, PMP and cadmium chloride hemidihydrate was tested against Escherichia coli, Staphylococcus aureus and Bacillus subtilis by the agar diffusion method.
