A Bimetallic Bis-pentalene Sandwich Complex: Synthesis and Structure of Mo2[C8H4(1,4-SiPri3)2]2
摘要:
The reaction between K-2[C8H4(1,4-SiPr3i)(2)] and Mo-2(OAc)(4) yields Mo-2[C8H4(1,4-SiPr3i)(2)](2), the first example ofa 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 degrees and 3 degrees while the SiPr3i groups are staggered the Mo-Mo distance is 2.340(1) Angstrom.
