Gallium(II) sulfide GaS is a chemical compound of gallium and sulfur. The normal form of gallium(II) sulfide as made from the elements has a hexagonal layer structure containing Ga24+ units which have a Ga-Ga distance of 248pm. This layer structure is similar to GaTe GaSe and InSe. An unusual metastable form with a distorted wurtzite structure has been reported as being produced using MOCVD.
