Description
Alexander Gerstner and four co-authors report new sandwich compounds built on a ring system that holds two boron atoms. With one portion of a chromium reagent, the ring bound the metal unit on a single face. With two portions, chromium, molybdenum, or tungsten units sat on both faces, one above and one below the ring plane. A twofold reduction then gave a doubly charged version of the ring, held between two lithium units.
That reduced ring reacted with chromium and molybdenum reagents to give the first stable zero-valent metal sandwich compounds of this kind. The team checked every new compound with several forms of spectroscopy and with X-ray crystal structures. Computer calculations added a picture of the bonding inside the rings and the chromium compounds.
