| Abstract: | Inventing new wheels: reaction of M(3)(CO)(12) ] (M=Ru, Os) with 4-RC(6)H(4)SH afforded {M(S-4-RC(6)H(4))(2)(CO)(2)}(8)] (R=H; I) or {M(S-4-RC(6)H(4))(2)(CO)(2)}(6)] (R=Me, iPr; II; see scheme), all of which have been structurally characterized. The octamers I are unique metal molecular wheels featuring skew-edge-shared octahedra with a central planar M(8) octagon. {Ru(S-4-iPrC(6)H(4))(2)(CO)(2)}(6)] selectively binds a Cu(+) or Ag(+) ion to form M'{Ru(S(4-iPr-C(6)H(4)))(2)(CO)(2)}(6)](+) (III). |
