Monoorganotin–polyoxometal-compounds. Part IV: Na2[(iPrSn3)(OV)4O10(OH)3]·5H2O·3DMSO, a novel branched tetravanadate(V) stabilized by a trimeric monoorganotin-oxo-hydroxo unit
摘要:
Via self-assembly of the molecular precursors sodium orthovanadate and isopropyltin-dihydroxide-chloride the unprecedented organic-inorganic hybrid polyoxoanion [((PrSn)-Pr-i)(3)(OV)(4)O-10(OH)(3)](2) was synthesized in dimethylsulfoxide (DMSO) and isolated as its sodium salt Na-2[((PrSn)-Pr-i)(3)(OV)(4)O-10(OH)(3)]center dot 5H(2)O center dot 3DMSO. This spherical nanosized anion is composed of two different structural subunits, a well-known trinuclear monoorganotin-polyoxo-hydroxo unit with octahedrally coordinated tin atoms and a new open-chain, branched isopolyoxo tetravanadate(V) with tetrahedrally coordinated vanadium atoms.
