Di-μ(2)-ethano­lato-octa­methyl­bis­(μ-4-methyl-5-sulfanyl­idene-4,5-dihydro-1H-1,2,4-triazol-1-ido-κ(2) N (1):N (2))di-μ(3)-oxido-tetra­tin(IV)

The tetra­nuclear title compound, [Sn(4)(CH(3))(8)(C(2)H(5)O)(2)O(2)(C(3)H(4)N(3)S)(2)], lies about a center of inversion; the mol­ecule features a three-rung-staircase Sn(4)O(4) core in which two Sn(IV) atoms are bridged by the 4-methyl-5-sulfanyl­idene-4,5-dihydro-1H-1,2,4-triazol-1-ide group.

Sumario:The tetra­nuclear title compound, [Sn(4)(CH(3))(8)(C(2)H(5)O)(2)O(2)(C(3)H(4)N(3)S)(2)], lies about a center of inversion; the mol­ecule features a three-rung-staircase Sn(4)O(4) core in which two Sn(IV) atoms are bridged by the 4-methyl-5-sulfanyl­idene-4,5-dihydro-1H-1,2,4-triazol-1-ide group. The negatively charged N atom of the group binds to the terminal Sn(IV) atom at a shorter distance [Sn—N = 2.240 (3) Å] compared with the neutral N atom that binds to the central Sn(IV) atom [Sn← N = 2.641 (3) Å]. The terminal Sn(IV) atom is five-coordinate in a cis-C(2)SnNO(2) trigonal–bipyramidal geometry [C—Sn—C = 127.5 (2)°], whereas the central Sn(IV) atom is six-coordinate in a C(2)SnNO(3) skew-trazepoidal bipyramidal geometry [C—Sn—C = 145.0 (2)°].
