The isolation and characterization of [CpRu(9S3)](O3SCF3), where 9S3 = 1,4,
7-trithiacyclononane, is reported. The title compound crystallizes in the o
rthorhombic space group Pbca: a = 10.2542(18), b = 14.8991(13), c = 22.4832
(18) Angstrom, and Z = 8. The Ru atom is sandwiched between the rr-bound cy
clopentadienyl ligand and the 983 ligand, bonding to all three of the sulfu
r atoms in the 9S3. The Ru-S distances are 2.2991(10), 2.2979(11), and 2.30
55(10) a. The C-S distances range from 1.819(4) to 1.852(5) Angstrom in the
trithiacyclononane ring.
