Poly[[aquadi-μ3-malonato-hexaphenylditin(IV)] acetone solvate]

Abstract

The asymmetric unit of the title polymeric complex, {[Sn2=(C6H5)6(C3H2O4)(H2O)]·C3H6O}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.
