catena-Poly[[diphenylpropyltin(IV)]-μ-chloroacetato-κ2O:O′]

The title compound, [Sn(C3H7)(C6H5)2(C2H2ClO2)]n, comprises polymeric carboxylate-bridged spiral chains with two monomer formula units in the asymmetric unit. Both Sn centres exhibit similar distorted trigonal–bipyramidal [C3SnO2] coordination, with the O atoms of the carboyxlate ligands in trans positions.
