Anhydrous penta-guanidinium dihydrogen nona-vanado(IV)platinate(IV)

, : Anhydrous penta-guanidinium dihydrogen nona-vanado(IV)platinate(IV). Acta Crystallographica. Section E, Structure Reports Online 67(Pt 12): M1801-2

The title compound, (CH(6)N(3))(5)[H(2)PtV(9)O(28)], containing the nona-vanadoplatinate(IV) polyanion, was obtained by hydro-thermal reaction. The polyanion has approximate C(2v) symmetry. The two Pt-bound μ(2)-O atoms are protonated in the polyanion. The heteropolyanions form inversion-generated dimers, {[H(2)PtV(9)O(28)](2)}(10-), held together by each of the two μ(2)-O-H⋯μ(2)-O and μ(2)-O-H⋯μ(3)-O hydrogen bonds. The guanidinium cations are hydrogen bonded with the μ(2)- and terminal O atoms of the polyanion, connecting the polyanions into a three-dimensional network.

Reverse time migration (RTM) was first introduced in the early 1980s (Whitmore, 1983), but was seemingly dormant until recent advances in computer hardware helped propel it onto the stage as a powerful depth-imaging method. RTM is now standard for...

Fatty acid amino acid conjugates (FACs) in the oral secretions of Lepidopteran larvae are responsible for eliciting plant defense responses. FACs are present despite fitness costs which suggests that they are important for larval survival. In prev...
