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.
