Abstract The Salen-copper(II) complex was synthesized by diffusion. The structure was characterized by single crystal X-ray diffraction. It crystallized in triclinic system,pB1spacegroup,with a=9.3441(18)Å, b=11.478(3)Å, c=12.320(3)Å, a=81.584(11)°, b=74.681(9)°, g=68.206(9), MolecularFormula: C23H19CuN5O8, M=397.86, V=1181.6(5)Å3, z=2, Dc=1.56Mg/m3, R1=0.0416, wR2=0.1236,I>[2s/(I)]. The crystal included a mononuclear complex [Cu(H2L)(DMF)] and a non-coordinated H2O molecular.

Abstracts d- MnO2 was prepared with hydrothermal treatment, and its crystalline structure was verified with X-ray diffraction spectroscopy. FTIR showed there were copious hydroxyl groups on the surface of d-MnO2 for the adsorption. The adsorption capacity of three kinds of heavy metal ions Pb2+, Cd2+ and Cu2+ on the d-MnO2 was all increased with the increase of ion concentration and the increase of […]

Abstract In this paper diethoxy-acrylamide methoxyl thiophosphate (DAMT) was synthesized with the reaction N-hydroxymethyl acrylamide and O, O-diethyl phosphorochloridothioate catalyzed by cuprous chloride in presence of triethylamine, and the flame retarded poly (DAMT-co-acrylonitrile) was obtained though free-radically copolymerized process. The properties of copolymer were estimated by Limiting Oxygen Index (LOI) values and thermogravimetric analysis (TGA). The […]
