introduction: developing new radiosynovectomy agents is of great importance due to the aging of human populations around the world and increasing the incidence of inflammatory diseases. in this work, sm-153 chitosan agent was developed for the first time in our country and preparation and quality control of the compound is described. methods: sm-153 chloride was obtained by thermal neutron flu...

A symmetric complex [NiL2(H2O)2]Cl2, where L = 2-picolylamine was synthesized and characterized by spectroscopic and structural methods. Single crystal X-ray studies reveal that the Ni(II) center located in a pseudo-octahedral N4O2 environment with bidentate ligands L positioned in basal and two water molecules in the apical position. The complex is solvatochromic, ionochromic and thermochromic...

The synthesis and single-crystal X-ray structure determination of the title compound (phen)Pb(02CMe) is described. The complex crystallizes in the monoclinic space group P2 /c, a = 7.823(3), b = 12.421(4), c = 9.262(2) ?, ? = 79.92(3)", Z = 4, yielding R 0.048 for 3210 independent reflections. The coordination number around the lead atom is six. [Pb-N 2.54(2), 2.56(4)],[Pb-0, 2.19-2.22]

The structure and properties of niobapyrimidinium complex were examined by density functionaltheory method (mpw1pw91). The effect of solvent on the structural parameters, frontier orbitalenergies and hyperpolarizability (tot) of this molecule has been explored. The thermodynamicproperties of the title compound at different temperatures have been calculated. Also, the parasubstitutionseffect on ...
