Germanide halides are compound that include the germanide (Ge) anion and a halide such as chloride (Cl), bromide (Br) or iodide (I). They include germanide iodides, germanide bromides or germanide chlorides. They can be considered as mixed anion compounds. They are in the category of tetrelidehalides. Related compounds include the silicide iodides, and carbide iodides.
