【 摘 要 】

In the structure of the hydrated title salt, (C4H7N2)2[Sn(C2O4)2(OH)2]·H2O, the asymmetric unit comprises one stannate(IV) dianion, two organic cations and one water mol­ecule of crystallization. The [Sn(C2O4)2(OH)2]2− dianion consists of an SnIV atom chelated by two oxalate anions and coordinated by two OH− ligands in a cis octa­hedral arrangement. Neighbouring anions are connected through O—H⋯O hydrogen bonds between hydroxide groups and non-coordinating oxalate O atoms into layers expanding parallel to (100). In addition, cations and anions are linked through N—H⋯O hydrogen bonds, and the water mol­ecule bridges two anions with two O—H⋯O hydrogen bonds and is also the acceptor of an N—H⋯O hydrogen bond with one of the cations. Weak C—H⋯O hydrogen bonds are also observed. The intricate hydrogen bonding leads to the formation of a three-dimensional network.
