Bis(dicyclohexylammonium) tungstate dihydrate, [NH₂(C₆H₁₁)₂]₂[WO₄]·2H₂O

W. Bi, D. Sun, R. Cao, J.-T. Chen and M. Hong

Abstract: The crystal structure of the title complex is built of dicyclohexylammonium cations, [NH₂(C₆H₁₁)₂]⁺, orthotungstate dianions, [WO₄]^2-, and lattice water molecules. The cations and coordinated water molecules occupy special positions on twofold axes; the tetrahedral orthotungstate dianion is located on a axis. Hydrogen bonds involving all N- and O-bound H atoms link the cations, anions and water molecules into an infinite three-dimensional aggregate. The crystal is isostructural with its molybdenum analog [Thiele & Fuchs (1979). Z. Naturforsch. Teil B, 34, 145-154].
