Organomagnesium compounds polymeric structures

Relatively little is known about the crystal structures of unsolvated organomagnesium compounds. From this viewpoint, our polymeric structures of [diphenylmagnesium] and of a [dineopentylmagne-sium neopentylmagnesium bromidel adduct contribute to fill a gap in... 

In the absence of coordinating solvents like ethers, most organomagnesium compounds tend to form polymeric structures. Microcrystalline solids or viscous liquids are generally obtained on desolvation of organomagnesium ether complexes, which are almost insoluble in apolar (non-...
