چکیده
The tetra-nuclear title compound, [Sn4(CH3)8(C2H5O)2O2(C3H4N3S)2], lies about a center of inversion; the mol-ecule features a three-rung-staircase Sn4O4 core in which two Sn(IV) atoms are bridged by the 4-methyl-5-sulfanyl-idene-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-C2SnNO2 trigonal-bipyramidal geometry [C-Sn-C = 127.5 (2)°], whereas the central Sn(IV) atom is six-coordinate in a C2SnNO3 skew-trazepoidal bipyramidal geometry [C-Sn-C = 145.0 (2)°].

In the title mol-ecule, C(16)H(16)N(4)O(2)S, the plane of the 1,2,4-triazole ring forms dihedral angles of 77.9 (2) and 30.0 (2)° with the planes of the furyl and phenyl rings, respectively. Weak inter-molecular N-H⋯S and C-H⋯O hydrogen bonds consolidate the crystal packing.
