Organozincates
Organozinc compounds that are strongly Lewis acidic are vulnerable to nucleophilic attack by alkali metals, such as sodium, and thus form these 'ate compounds'. Two types of organozincates are recognized: tetraorganozincates ([R4Zn]M2), which are dianionic, and triorganozincates ([R3Zn]M), which are monoanionic. Their structures, which are determined by the ligands, have been extensively characterized.
