- چکیده:
- چکیده انگلیسی: Two new mercury(II) Schiff base complexes [Hg((2,6-Cl-ba)2-1,2-pn)X2] (X = Cl (1), I (2) and (2,6-Cl-ba)2-1,2-pn = N,N'-bis(2,6-dichlorobenzylidene)-1,2-diaminopropane) have been synthesized and characterized by elemental analysis (CHN), FT-IR and 1H-NMR spectroscopy. The crystal structure of complexes 1 and 2 were determined by single-crystal X-ray diffraction. X-ray results shown that the mercury(II) ions in these complexes have a distorted tetrahedral geometry with HgN2Cl2 and HgN2I2 chromophores, respectively. In these complexes, the Schiff base ligand (2,6-Cl-ba)2-1,2-pn act as chelating bidentate ligand, coordinating via the two iminic nitrogen atoms and it adopts an E,E conformation. Finally, the thermal behavior of complexes was study using thermogravimetry in order to evaluate their thermal stability and thermal decomposition pathway.

- چکیده:
- چکیده انگلیسی: 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.- انتشار مقاله: 13-09-1396
