Bis[2-(3-chloro-benzyl-idene)propanoato-κO,O']diethyl-tin(IV)
Abstract:
In the mol-ecule of the title compound, [Sn(C(2)H(5))(2)(C(10)H(8)ClO(2))(2)], the Sn atom is six-coordinated in a distorted tetra-gonal-bipyramidal configuration by four O atoms in the equatorial plane and two C atoms in the axial positions. Intra-molecular C-H⋯O hydrogen bonds result in the formation of two planar and two non-planar five-membered rings; the latter adopt envelope conformations. There are weak π-π inter-actions between aromatic rings, with centroid-to-centroid distances of 3.796 (2) and 4.171 (2) Å. There is also a single C-Cl⋯π inter-action [C-Cl = 1.740 (4), Cl⋯π = 3.795 (2) C⋯π = 3.697 (4) Åand C-Cl⋯\p =73.45 (11)°].
