Abstract

Take five: A unique quintuply bonded dimolybdenum complex [Mo 2(μ-Li){μ-HC(N-2,6-Et 2C 6H 3) 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.
