Bis[tris(2,2'-bipyridyl-²N,N')iron(II)] cyclo-tetravanadate decahydrate

M.-H. Huang, L.-H. Bi and S.-J. Dong

Abstract: The hydrothermal reactions of metavanadate and divalent iron salts in the presence of nitrogen-donor chelating ligands yield the complex [Fe(C₁₀H₈N₂)₃]₂[V₄O₁₂]·10H₂O, which consists of one centrosymmetric eight-membered ring [V₄O₁₂]^4- anion cluster, formed by four VO₄ tetrahedra sharing vertices, two discrete octahedral [Fe(C₁₀H₈N₂)₃]²⁺ cations, formed by three 2,2'-bipyridyl ligands coordinated to Fe^II, and ten water molecules of solvation. The anion and coordination cations are isolated and form anion and cation layers, respectively. In the anion layers, these anions and water molecules of solvation are linked to each other, in a two-dimensional motif, through hydrogen-bonding interactions.
