Abstract

In the centrosymmetric tetra-nuclear title compound, [Sn(4)(C(4)H(9))(8)(C(7)H(5)O(3))(4)O(2)], one of the two independent Sn atoms is five-coordinate in a cis-C(2)SnO(3) trigonal-bipyramidal geometry [C-Sn-C = 142.7 (1)°]; the geometry is distorted owing to a long Sn⋯O(double bond) inter-action [Sn⋯O = 2.862 (1) Å]. The other Sn atom has a bent R(2)Sn skeleton [C-Sn-C = 144.0 (1)°], but the geometry is best regarded as being a trans-C(2)SnO(4) octa-hedron as the Sn-O(single bond) inter-action is shorter [Sn-O = 2.674 (1) Å].

摘要

在中心对称的四核标题化合物[Sn₄(C₄H₉)₈(C₇H₅O₃)₄O₂]中，两个独立的Sn原子之一呈五配位，具有顺式-C₂SnO₃三角双锥几何构型[C-Sn-C = 142.7 (1)°]；由于存在长的Sn⋯O（双键）相互作用[Sn⋯O = 2.862 (1) Å]，该几何构型发生扭曲。另一个Sn原子具有弯曲的R₂Sn骨架[C-Sn-C = 144.0 (1)°]，但由于Sn-O（单键）相互作用较短[Sn-O = 2.674 (1) Å]，其几何构型最好视为反式-C₂SnO₄八面体。
