title: Tris{4-[(2H-tetra-zol-5-yl)meth-yl]morpholinium} dodeca-tungstophosphate hexa-hydrate.
abstract: The title heteropolyoxidotungstate-based inorganic-organic hybrid material, (C(6)H(12)N(5)O)(3)[W(12)(PO(4))O(36)]·6H(2)O, consists of one α-Keggin-type [W(12)(PO(4))O(36)](3-) polyoxidometalate anion (POM), three crystallographically independent 4-[(2H-tetra-zol-5-yl)meth-yl]morpholinium cations and six water mol-ecules 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 inter-actions between the organic cations, inorganic anion and the crystal water mol-ecules lead to a three-dimensional structure. Moreover, six uncoordinated water mol-ecules increase the number of hydrogen bonds in the network and lead to the formation of (H(2)O)(∞) clusters.
