Bis(dicyclohexylammonium) Aquadimethyldi(oxalato-O,O')stannate Ethanol Solvate

The Sn atom in the title compound, [(C₆H₁₁)₂NH₂]₂[Sn(C₂O₄)₂(CH₃)₂(H₂O)].C₂H₆O, is chelated by two isobidentate oxalato groups and it exists in a trans-C₂SnO₅ pentagonal-bipyramidal environment [C-Sn-C 173.5 (2)°] . The coordinated water molecule is hydrogen bonded to a carbonyl O atom of an adjacent stannate [O...O = 2.796 (3) Å] to form a centrosymmetric dinuclear tetraanion. These are linked into sheets through the two ammonium cations [N...O 2.783 (3), 2.790 (3), 2.793 (3), 2.848 (3) Å]. The ethanol solvate molecule is hydrogen bonded to another doubly bonded carbonyl O atom [O...O = 2.819 (9) Å].
