摘要

Synthesis, infrared spectroscopy and crystal structure of a new potassium decavanadate decahydrate, K_6[V_(10)O_(28)] ?10H_2O, has been reported. The infrared spectrum is dominated by decavanadate polyanion and water bands. The X-ray crystallography analysis found the compound crystallizes in a triclinic system with the parameters a = 10.5334 (4) ?, b = 10.6600 (4) ?, c = 17.7351 (5) ?; α = 76.940 (2)°, β = 75.836 (2)°, γ = 64.776 (2)°; V = 1,729.86 (11) ?3; Z = 2, space group Poverline{1}. The polyanion consists of ten [VO_6] octahedra sharing edges, in which the V-O distances are in good agreement with those reported for other decavanadates. The crystal structure is stabilized by potassium cations and water molecules forming a complex pattern of hydrogen bonding and short contact ionic interactions. Graphical Abstract: Synthesis, infrared spectroscopy and crystal structure of a new potassium decavanadate decahydrate, K _6[V_(10)O_(28)]?10H_2O are described. The infrared spectrum is dominated by decavanadate polyanion and water bands. The crystal structure shows a complex pattern composed by hydrogen bonds and short contacts between potassium cations and water molecules.[Figure not available: see fulltext.]
