The reaction between K2[C8H4(1,4-SiPri3)2] and Mo2(OAc)4 yields Mo2[C8H4(1,4-SiPri3)2]2, the first example of a bimetallic bis-pentalene sandwich complex to be structurally characterized by X-ray diffraction. Structural data show that the carbon frameworks of the two pentalene ligands are eclipsed and effectively planar with fold angles of ca. 2° and 3° while the SiPri3 groups are staggered; the Mo−Mo distance is 2.340(1) Å.
