Abstract: The asymmetric unit of the title organotin(IV) compound, [Sn(C4H9)2(C5H3N2O2)2(H2O)], contains one-and-a-half molecules. The half-molecule is completed by crystallographic twofold symmetry, with its Sn and water O atoms lying on the rotation axis. Both molecules feature seven-coordinate Sn atoms in trans-C2SnN2O3 pentagonal-bipyramidal coordination environments. The carboxylate anions N,O-chelate to the Sn atom. In the crystal, the carboxylate O atoms not involved in coordination serve as acceptors for O-HO hydrogen bonds from adjacent water molecules, generating a three-dimensional network.
