Bis-mu-hydroxo-bis[(benzyl)(nitrosyl-N)(eta(5)-pentamethylcyclopentadien yl)-molybdenum]

The title complex, [Mo-2(OH)(2)(NO)(2)(C7H7)(2)(C10H15)(2)], was obtained in 19% isolated yield from the treatment of [Mo(NO)(CH(2)Ph)(OCMe(3))(C10H15)] in tetrahydrofuran with H-2 (276 kPa). A single-crystal X-ray crystallo-graphic analysis confirmed its bimetallic nature, the near planarity of the central Mo2O2 core and the monohapticity of the CH(2)Ph ligands. The complex is diamagnetic (X(M) = -517 x 10(-6) cm(3) mol(-1)) at room temperature and its H-1 NMR spectrum in C6D6 indicates that it exists as a mixture of isomers in this solution.
