The title heteropolyoxidotungstate-based inorganic–organic hybrid material, (C6H12N5O)3[W12(PO4)O36]6H2O, consists of one -Keggin-type [W12(PO4)O36]3 polyoxidometalate anion (POM), three crystallographically independent 4-[(2Htetrazol- 5-yl)methyl]morpholinium cations and six water molecules of crystallization. The morpholine ring of the cation adopts a chair conformation. The anion shows characteristic features with respect to bond lengths and angles. An extensive network of N—H  O, N—H  N, O—H  O and O—H  N hydrogen-bonding interactions between the organic cations, inorganic anion and the crystal water molecules lead to a three-dimensional structure. Moreover, six uncoordinated water molecules increase the number of hydrogen bonds in the network and lead to the formation of (H2O)1 clusters.
