By Babak Feizyzadeh, Masoud Mirzaei, Hossein Eshtiagh-Hosseini and Ahmad Gholizadeh


The title heteropolyoxidotungstate-based inorganic–organic hybrid material, (C6H12N5O)3[W12(PO4)O36]·6H2O, consists of one α-Keggin-type [W12(PO4)O36]3− polyoxidometalate anion (POM), three crystallographically independent 4-[(2H-tetra­zol-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)∞ clusters
