Description:
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.
