The title compound, hexaammonium tetra-μ3-selenido-tetrakis(tricyanomolybdenum) hexahydrate, is isostructural with the Mo/S, W/S and W/Se analogues. The structure contains disordered cyclic hydrogen-bonded [{(NH4)(H2O)}3]3+ cations and [Mo4Se4(CN)12]6- cluster anions with 4̄3m symmetry. The cation assembly consists of alternating ammonium and water molecules linked by N-H⋯O hydrogen bonds. The anion has a typical cubane cluster structure. The cations and anions are linked together by hydrogen bonds involving the terminal N atoms of the CN groups.
