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 .
