Abstract

In this research, 1D four-coordinate copper(I) coordination Polymer [Cu(Clba2-1,2-pn)(NCS)]n (1) with thiocyanate anion as bridging ligand, where Clba2-1,2-pn = N,Nʹ-bis(2,4-chlorobenzylidene)propane-1,2-diamine), was synthesized by slow evaporation of solvent at room temperature and characterized by elemental analysis (CHN) and single-crystal X-ray diffraction. Microparticles of 1 were prepared by an ultrasonic bath assisted synthesis and characterized
by Scanning Electron Microscopy (SEM) and elemental analysis. Thermal stability of 1 was studied by ThermoGravimetry (TG) and Differential Thermal Analysis (DTA). The structure of 1 consists of 1D polymeric chain in which copper(I) ions are bridged by two thiocyanate groups in an end-to-end fashion, with Cu
×××Cu separation 5.686(4) Å.
