Abstract: The title complex, [Sn₃(C₇H₇F)₆(CH₃O)₂(C₂N₂S₃)O]·0.5C₆H₆, contains a unique ₃-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) Å; the remaining two Sn atoms (with C₂O₂N ligand sets) have Sn-O distances ranging from 2.038 (5) to 2.188 (5) Å. The two Sn-N bond lengths are 2.217 (5) and 2.225 (6) Å, and the six Sn-C bond lengths range from 2.125 (8) to 2.150 (8) Å. There are no clasical hydrogen bonds in the crystal structure.
