[μ 2 -2,5-Dimercapto-1,3,4-thiadiazole(2–)-κ 2 N : N ]bis(μ 2 -methanolato)-μ 3 -oxido-tris[bis(4-fluorobenzyl)tin(IV)] benzene hemisolvate

The title complex, [Sn3(C7H7F)6(CH3O)2(C2N2S3)O]·0.5C6H6, contains a unique μ3-OSn3N2O2 central core with three five-coordinated Sn atoms with distorted trigonal–bipyramidal geometries; the benzene mol­ecule resides on a crystallographic inversion center (at the ring centroid). One Sn atom (with a C2O3 ligand set) has Sn—O bond lengths in the range 2.044 (4)–2.131 (5) A; the remaining two Sn atoms (with C2O2N ligand sets) have Sn—O distances ranging from 2.038 (5) to 2.188 (5) A. The two Sn—N bond lengths are 2.217 (5) and 2.225 (6) A, and the six Sn—C bond lengths range from 2.125 (8) to 2.150 (8) A. There are no clasical hydrogen bonds in the crystal structure.
