Crystal structure of pentapotassium dihydrogen nonavanadato(V)platinate(IV) nonahydrate

Abstract

The polyanion in K5[H2PtV9O28]·9H2O has approximate mm2 (C 2v) symmetry. The two platinum-bound μ2-O atoms are protonated in the polyanion. The heteropolyanions form inversion-generated dimers, {[H2PtV9O28]2}10−, held together by μ2-O—H⋯μ2-O and μ2-O—H⋯μ3-O hydrogen bonds.

Double salt crystal structure of hexasodium hemiundecahydrogenα-hexamolybdoplatinate(IV) heminonahydrogenα-hexamolybdoplatinate(IV) nonacosahydrate: dihydrogen disordered-mixture double salt

“…Furthermore, we have reported the stepwise protonation species in ISSN 2056-9890 the nonavanadoplatinate(IV) series, viz. [H n PtV 9 O 28 ] (7Àn)À (n = 2 and 3) (Lee et al, 2008;Joo et al, 2011;Joo & Lee, 2015;Joo et al, 2015b). As well as the Pt IV a Keggin-type (Keggin, 1934) heteropolyoxometalate was formed, [-SiPt IV 2 W 10 O 40 ] 8À (Lee et al, 2003).…”
