چکیده
The tetra-nuclear title compound, [Sn4(CH3)8(C3H7O)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 = 2.236 (2) Å] compared with the neutral N atom that binds to the central Sn(IV) atom [Sn← N = 2.805 (2) Å]. The terminal Sn(IV) atom is five-coordinate in a cis-C2SnNO2 trigonal-bipyramidal geometry [C-Sn-C = 136.4 (1)°], whereas the central Sn(IV) atom is six-coordinate in a C2SnNO3 skew-trazepoidal bipyramidal geometry [C-Sn-C = 145.4 (1)°]. The C atoms of the isopropoxy group are disordered over two positions in a 0.591 (7):0.409 (7) ratio.

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.
