INDIUM(III) THIOLATE-BRIDGED MOLYBDENOCENE COMPLEXES - CRYSTAL-STRUCTURE OF OCP(2)(MU-SET)(2))(2)][BPH(4)]CENTER-DOT(CH3)(2)CO

The reaction of [MoCp(2)(SR)(2)] (R=CH3, C2H5, n-C14H29 or C6H5) with InCl3 in ethanol affords new compounds which, after treatment with NH4 PF6, were fully characterized as the hexafluorophosphate salts [In{MoC p(2)(mu-SR)(2))(3)][PF6](3). A new monocation [InCl2(MoCp(2)(mu-SR)(2) }(2)](+) was isolated as a tetraphenylborate salt and structurally cha racterized by a single-crystal X-ray diffraction study. The molybdenum atoms exhibit the usual bent metallocene structure with a distorted t etrahedron around each metal atom. The coordination around the indium atom is cis-octahedral. The InS4Cl2 core has a pseudo two-fold symmetr y axis through the In atom bisecting the midpoint of the Cl-Cl edge of the coordination polyhedron. This pseudosymmetry extends to the Mo at oms and to some extent to the Cp ligands. The In-Mo distances, 4.0401( 5) and 4.0703(5)Angstrom, and the large In-S-Mo angles indicate no int eraction between the two different metal centres.
