An Electron-Rich Molybdenum-Molybdenum Quintuple Bond Spanned by One Lithium Atom

Take five: A unique quintuply bonded dimolybdenum complex [Mo2(μ‐Li){μ‐HC(N‐2,6‐Et2C6H3)2}3] (see picture) was synthesized and characterized. The MoMo interaction includes an unexpected bridging Li+ ion. Calculations indicate the bridging Li+ ion does not perturb the MoMo bond length (2.0612(4) Å)...

Zusammenfassung:	Take five: A unique quintuply bonded dimolybdenum complex [Mo2(μ‐Li){μ‐HC(N‐2,6‐Et2C6H3)2}3] (see picture) was synthesized and characterized. The MoMo interaction includes an unexpected bridging Li+ ion. Calculations indicate the bridging Li+ ion does not perturb the MoMo bond length (2.0612(4) Å), but results in a relatively small effective MoMo bond order of 3.67.
