Magnesium sandwich species

By the description magnesium sandwich species are meant compounds with the general structural formula [(CH)m]nMgp (and their substituted and/or ionized derivatives) where m 3, n 2 and p 1. In addition, it is tacitly assumed that the (CH) rings are attached to the metal by at least three carbons, i.e., that they are species with k > 3. [Pg.122]

The classic (if not classical) metal sandwich species bis(cyclopentadienyl)iron has the formula [(CH)5]2Fe (CpaFe) and the semisystematic name ferrocene, and so the related magnesium-containing species [(CHfsJaMg (CpaMg) is often accompanied by the name magnesocene. We commence our discussion with this species. [Pg.122]

This is not surprising—there are many textbook discussions of the difference between transition and main group elements. Consonant with this is the finding that (Cp )2Mg (the sandwich species alternatively called bis(pentamethylcyclopentadienyl)magnesium and decamethyfinagnesocene) does not react with CO, unlike the corresponding species with Ca and some other metals and metalloids . Indeed, in (Cp )2Mg, there is little room for another ligand around the central metal and Mg seems electronically satisfied. [Pg.125]
