| Abstract: [Mn(ECZ)3](NO3)2 is newly prepared by the aqueous solutions of Mn(NO3)2 and ethyl carbazate (ECZ). The crystal structure has been determined by X-ray crystal diffraction analysis. It belongs to monoclinic with space group of P21/n. The crystal parameters are: a=1.3974(2) nm, b=0.8796(2) nm, c=3.4322(7) nm, β=91.25(1) °, V= 4.2175(1) nm3, Z=8. Its molecular weight is 491.30. Mn2+ is located on the center of the molecular structure. Ethyl carbazate serves as a bidentate ligand which coordinates to the metal cations with its carbonyl oxygen atom and the terminal hydrazine nitrogen atom, forming five-member chelating rings, and three such rings are formed in each molecule. The coordination number of the metal ion is six and the coordination configuration of the central ion is octahedral. Specially, antimer configuration phenomenon is found in the molecule. The complex is further characterized by element analysis and IR measurements. The thermal decomposition mechanism is studied by using TG-DTG and DSC techniques. CCDC: 215675. | |
