DINUCLEAR THIOETHER HALF-SANDWICH RUTHENIUM(II) COMPLEXES OF THE TYPES [(RUL'([9]ANES(3)))(2)(MU-L)(N)](2-L)(2)](2+) AND [(RU([9]ANES(3)))(2)(MU-L)(3)](+) WITH HETEROCYCLIC THIOAMIDES L ([9]ANES(3)=1,4,7-TRITHIACYCLONONANE)() (N=1, L'=PPH(3), N=2, L'=MECN), [(RU([9]ANES(3)))(2)(MU)

Reaction of )][CF3SO3](2)([9]aneS(3)=1,4,7-trithiacyclononane) with 1, 3-benzothiazol-2-thione (Hbtt) and pyridine-2-thione (Hpyt) in methano l in a 1:1 molar ratio afforded dinuclear complexes {Ru([9]aneS(3)-KAP PA(3)S)}(2)(mu-L)(2)][CF3SO3](2) (L=btt or pyt) in which the ligands e xhibit a tridentate mu-1KAPPAS:2KAPPA(2)N,S bridging mode. Crystalliza tion of the btt complex from acetonitrile yielded )([9]aneS(3)-KAPPA(3 )S)}(2)(mu-btt)(2)][CF3SO3](2) with mu-S bridging ligands. A triply mu -S bridged complex [{Ru([9]aneS(3)-KAPPA(3)S)}(2)(mu-btt)(3)][CF3SO3] was obtained from [Ru(MeCN)(3)([9]aneS(3)-KAPPA(3)S)][CF3SO3](2)and bt t(-) in a 2:3 molar ratio. Fragments (Ph(3)P)([9]aneS(3)-KAPPA(3)S)Ru- II can be bridged with tetra- or tri-dentate dtuc(2-) (H(2)dtuc=2,4-di thiouracil) anions in Ru(PPh(3))([9]aneS(3)-KAPPA(3)S)}(2)(mu-dtuc)](2 +) and )}(mu-dtuc){Ru(PPh(3))([9]aneS(3)-KAPPA(3)S)}](+). The structur es of four complexes have been determined by X-ray crystallography.
