Abstract

The redetermined structure [for the previous study, see: Godfrey & Waters (1975 ▸). Cryst. Struct. Commun. 4, 5-8] of ammonium μ-oxido-μ-[1,5,6-tri-hydroxy-hexane-2,3,4-tris-(olato)]bis-[dioxidomolybdenum(V)] monohydrate, NH₄[Mo₂(C₆H₁₁O₆)O₅]·H₂O, was obtained from an attempt to prepare a glutamic acid complex from the [Co₂Mo₁₀H₄O₃₈]^6- anion. Subsequent study indicated the complex arose from a substantial impurity of mannitol in the glutamic acid sample used. All hydrogen atoms have been located in the present study and the packing displays N-H⋯O, O-H⋯O and C-H⋯O hydrogen bonds. A Hirshfeld surface analysis was also performed.
