K-5[W4O8(H2BO4)(HPO4)(2)(PO4)(2)]center dot 0.5H(2)O: A tungsten borophosphate with a novel sandwich-like layered structure
The first tungsten borophosphate compound, K-5[W4O8-(H2BO4)(HPO4)(2)(PO4)(2)] center dot 0.5H(2)O, has been synthesized under mild hydrothermal conditions, and the crystal structure with a new stoichiometry (B:P ratio 1:4) exhibits a novel sandwich-like layered structure.
