Organocadmium chemistry

An organocadmium compound is an organometallic compound containing a carbon to cadmium chemical bond. Organocadmium chemistry describes physical properties, synthesis, reactions and use of these compounds.[1] Cadmium shares group 12 with zinc and mercury and their corresponding chemistries have much in common.

Dimethylcadmium is a linear molecule with C-Cd bond lengths of 211.2 pm. All organocadmium compounds are sensitive to air, light and moisture.
