摘要
The first bridged osmocene compound, 1,2,3-trithia[3]osmocenophane (1), has been prepared by the reaction of 1,1'-dilithioosmocene with elemental sulphur, and its crystal structure determined by X-ray diffraction methods. The S-S bond lengths are 2.039(9) and 2.055(9) angstrom and the S-S-S bond angle is 106.4(4)-degrees. The S-C bond lengths are 1.760(12) and 1.752(11) angstrom with S-S-C bond angles of 103.1(5) and 103.5(5)-degrees. The cyclopentadienyl rings are in an eclipsed conformation and are slightly inclined to each other, with a non-bonded S(l)-S(3) separation of 3.279 angstrom.
