Di­aqua­di­chloro­di­phenyl­tin(IV) 18-crown-6

Di­aqua­di­chloro­di­phenyl­tin(IV) 18-crown-6, [SnCl₂(C₆H₅)₂(H₂O)₂]·C₁₂H₂₄O₆, adopts an all-trans octahedral configuration at the Sn atom. The coordinated water mol­ecule forms a pair of hydrogen bonds to the polyether to furnish a linear hydrogen-bonded chain structure. There are two half-mol­ecules of each component in the asymmetric unit, with the Sn atoms and the centres of the crown ethers lying on inversion centres.
