Poly[[aquadi-μ(3)-malonato-hexaphenyl­ditin(IV)] acetone solvate]

The asymmetric unit of the title polymeric complex, {[Sn(2)=(C(6)H(5))(6)(C(3)H(2)O(4))(H(2)O)]·C(3)H(6)O}(n), comprises of two Sn cations, one malonate anion and a non-coordinating acetone solvent mol­ecule. Both crystallographically independent Sn cations are five-coordinated by two O and three C atoms in a distorted trigonal-bipyrimidal geometry. One of the Sn cations is bridged by the malonate units, affording polymeric chains which run along [001]. Weak intra­molecular C—H⋯π inter­actions stabilize the mol­ecular structure. In the crystal structure, adjacent chains are inter­connected by inter­molecular O—H⋯O and C—H⋯O hydrogen bonds into a three-dimensional supra­molecular structure. A weak inter­molecular C—H⋯π inter­action is also observed.
