Tetra-ammonium μ-ethyl-enedi-amine-tetra-acetato-1κ³ O,N,O':2κ³ O'',N',O'''-bis-[trioxidotungstate(VI)] tetra-hydrate.

ABSTRACT: The title compound, (NH₄)₄[W₂(C₁₀H₁₂N₂O₈)O₆]·4H₂O, was obtained from a mixture of tungstic acid, ammonia and ethyl-enedi-amine-tetra-acetic acid (H₄edta) in a 2:4:1 ratio. The anion of the complex contains two WO₃ units and one bridging edta^4- ligand. Each central metal atom is tridentately coordinated by nitro-gen and two carboxyl-ate groups of the edta^4- ligand, together with the three oxido ligands, producing a distorted octa-hedral coordination environment around each tungsten atom. The center of the carbon-carbon bond of the ethyl-ene bridge represents a crystallographic inversion center. The crystal structure consists of a three-dimensional su
