Bis(cyclo­pentenylacetato)tetra­ethyl­distannoxane dimer

The mol­ecular structure of the title compound, tetra-μ₂-(cyclo­pent-2-en­yl)acetato-1:2κ²O:O′;1:3κ²O:O′;2:4κ²O:O′;3:4κ²O:O′-octa­ethyl-1κ²C,2κ²C,3κ²C,4κ²C-di-μ₃-oxo-1:2:3κ³O;2:3:4κ³O-tetra­tin, [Sn₄(C₂H₅)₈(C₇H₉O₂)₄O₂], is composed of two independent centrosymmetric dimers lying about inversion centers. In each dimer, the central Sn₂O₂ core is fused with two four-membered (Sn₂O₂) and two six-membered (Sn₂O₃C) rings. The endocyclic Sn atoms are six-coordinate in a skew-trapezoidal bipyramidal environment. The exocyclic Sn atoms are five-coordinate and show disotorted trigonal–bipyramidal geometry. The cyclo­pentenylacetate ligand shows different modes of coordination with tin. In both dimers, the Sn—C distances lie in a very narrow range [2.118 (4)–2.134 (4) Å], while the Sn—O distances range between 2.042 (2) and 2.314 (3) Å for strong bonds and between 2.638 (3) and 2.658 (3) Å for relatively weaker Sn—O bonds.
