چکیده
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].

In the centrosymmetric tetra-nuclear title complex, [Sn(4)(C(4)H(9))(8)(C(3)H(3)Br(2)O(2))(4)O(2)], one of the two independent Sn atoms is five-coordinated by one O atom of the carboxyl-ate anion, two bridging O atoms and two n-butyl groups in a C(2)SnO(3) distorted trigonal bipyramidal geometry. The other Sn atom also has a distorted trigonal bipyramidal geometry, being coordinated by two O at...

The title compound, [Sn(4)(C(8)H(17))(8)O(2)(C(6)H(5)N(2)O(2))(4)], is a tetra-nuclear Sn(IV) complex, built up by inversion symmetry around the central Sn(2)O(2) ring. The Sn(IV) coordination geometries are distorted SnO(3)C(2) trigonal-bipyramidal and distorted SnO(4)C(2) octa-hedral. The three-coordinate μ(3)-oxido bridging O atom in the Sn(2)O(2) ring is attached to three Sn atoms. All non-...
