Synthesis Crystal And Characterization Of The Transition Metal Complexes

This paper proposed six novel structure of POMS contained transition metal by control solution pH value and using hydrosol and hydrothermal technique,the elements analvsis and TG determine their patents for: (H2en)3(Hen)2[Na2Mov12vO24(OH)6(H2PO4)2(HPO4)4(PO4)2]·4H2O (1) (H2en)(Hen)5[CuNaMo12vO24(OH)6(H2O)(H2PO4)2(HPO4)4(PO4)2]·5H2O(2) (H3O)7[AsMo8O3o] (3) H[{Cr(OOCCH3)2(H2O)}3O]2[CrMo6O24H6]·24H2O(4) [Cu(OOCCH3)2(H2O)]2.5(5) (Mn2Mo2NaO5)(OH)5(6)Their crystal frame were confirmed via IR and X-ray single crystal. Compound 1 is Triclinic crystal department, P-1 space group, which is linked by Na[P4Mo6]2 unit and Na atoms bond to two-dimensional layered structure throughμ-O.Compound 2 is Triclinic crystal department, P-1 space group,{Na[Mo6P4]2} building blocks connected [CuO4(H2O)] quadrangular pyramid into two-dimensional layered framework, which through hydrogen bonds to form three-dimensional supramolecular Structure. Compound 3 is Orthorhombic crystal department, Cmcm space group, [AsMo8O3o]/. with D2h symmetry,a {AsO4} tetrahedron connecting two {MO4O15} groups. Compound 4 is Triclinic crystal department, P-1 space group, the compound is composed of an Anderson [CrMo6O24H6] structure and [{Cr(OOCCH3)2(H2O)}3O],which form 2D structure by hydrogen bonds. Compound 5 is Monoclinic crystal department, C2/c space group, which is 3D structure formed by the Cu and CH3COO- through hydrogen bonds. Compound 6 is Monoclinic crystal department, C2 space group, the transition metal manganese atoms take eight octahedral coordination, Molybdenum atoms take rare tetrahedral coordination,[MnO6] octahedral,[MoO4] and [NaO6] through angle and edge to form three-dimensional infinite network structure.We also studied the thermal stability and electrochemical properties of the complex synthesis.
