摘要：

Structures of Grignard reagents determined by X-ray diffraction, as of the end of August 1992, have been reviewed. There are two preparative procedures reported for the 24 structures, which include monomers, dimers and oligomers. The hard Mg(II) atom is found in a tetra-, penta- and hexacoordinate environment with ligands ranging from soft, through borderline to hard. The most common halogen associated with these Grignard structures is bromine. The carbon donor ligands are uni-, bi- or pentadentate. Relationships between structural parameters, covalent radii of coordinated atoms and the geometry of the coordination sphere are discussed.
