A new complex of hexaammonium bis(1-oxyethylidenediphosphonate)dioxomolybdenum tetrahydrate (NH4)6[MoO2(L)2] · 4H2O (I) (H4L is H2O3P–C(OH)(CH3)–PO3H2) is synthesized. Its molecular structure consisting of the complex anion [MoO2L2]6–, six out-of-sphere ammonium cations \({\text{NH}}_{{\text{4}}}^{ + }\), and four water molecules is determined by X-ray diffraction analysis (CIF file CCDC no. 813517). The solubility of complex I is studied. The changes in the IR absorption spectra upon complex formation are discussed.
