The new antimonato polyoxovanadate [VIV16SbIII4O42(H2O)]8− cluster (1a) is the main structural motif of the solvothermally obtained compound {(trenH2)Zn(tren)}2[V16Sb4O42(H2O)]·xH2O (x = 6–10) (1) (tren = tris(2-aminoethyl)amine). The C2-symmetric cluster structure is closely related to the {V18O42} archetype. 1 crystallizes in the monoclinic space group C2/c with a = 30.7070(19) Å, b = 13.9512(5) Å, c = 23.1435(14) Å, β = 128.076(6)°, and V = 7804.8(7) Å3. The orientation of the [SbIII2O5]4− groups in each cluster leads to intermolecular Sb⋯O contacts and the formation of channels between the clusters. [Zn(tren)(trenH2)] complexes with trigonal bipyramidal coordination environments are located between the [V16Sb4O42(H2O)]8− anions, and form a three dimensional network with them via strong N–H⋯O hydrogen bonds. Up to 250 °C crystal water molecules are emitted, which are reversibly incorporated in humid air.
