Abstract: The title compound, tetrapotassium bis(glycine)hexacosaoxooctamolybdenum(VI) hexahydrate, K₄[Mo₈O₂₆(NH₃CH₂COO)₂]·6H₂O, consists of a molecular network of centrosymmetric [Mo₈O₂₆(NH₃CH₂COO)₂]^4- anions, K⁺ cations and water molecules, which interact by an extensive hydrogen-bonding network. The [Mo₈O₂₆(NH₃CH₂COO)₂]^4- anion is constructed from MoO₆ and MoO₅(OOCCH₂NH₃) octahedral units, where the latter has O atoms of terminal and bridging oxo groups as well as those of glycine ligands.
