The compound, Cs 3 CdH 5, prepared by the reaction of caesium hydride, CsH, and cadmium metal powder at high temperature contains the CdH 2− 4 ion, along with caesium cations, Cs +, and hydride anions, H −. The tetrahedral anion is an example of an ionic complex of CdH 2. The average Cd-H bond length in CdH 2− 4 is 182pm.
Cadmium sulfide is the inorganic compound with the formula CdS. Cadmium sulfide is a yellow salt. It occurs in nature with two different crystal structures as the rare minerals greenockite and hawleyite, but is more prevalent as an impurity substituent in the similarly structured zinc ores sphalerite and wurtzite, which are the major economic sources of cadmium.
