Vyderzhka: Sulʹfíd lítiya, sernistyĭ litiĭ - Li2S, nyeorganicheskoe binarnoe soedinenie, litievaya solʹ serovodorodnoĭ kisloty. Sulʹfid litiya predstavlyaet soboĭ svetlo-zhëltoe ili bestsvetnoe kristallicheskoe veshchestvo, kharakterizuyushchyeesya granetsentrirovannoĭ kubicheskoĭ reshëtkoĭ tipa flyuorita (a = 0,571 nm, z = 4, prostranstvennaya gruppa Fm3m), khorosho rastvorimoe v vode, rastvorimoe v spirte.
