Synthesis and Crystal Structure of a Novel Compound of (C2N2H8O2) H6V10O28
A novel vanadate decamer, involving all vanadium atoms present in +5 oxidation and one formhydroxamic acid dimer cation readical, has been synthesized. The single-crystal X-ray diffraction shows that the orange crystal is formed in the triclinic system, space group Pī, a = 8. 4960 (17), b = 10. 447 (2), c = 11. 299 (2)A, α = 68. 82 (3)°,β = 87. 35 (3)°, γ= 66. 97 (3)°. V = 855. 3(3)A3, Z = 8, R1 = 0. 0857, wR2 = 0. 2551. X-ray crystallographic and packing in superlattice studies showed that the crystal structure was constructed by electrostatic attraction of O―H…O hydrogen bonds between formhydroxamic acid dimer cation and decavanadate polyanion. Formhydroxamic acid dimer is got through controlling the condition of the reaction using formhydroxamic acid.
