Most of the halides of alkali metals, oxides and sulphides of alkaline earth metals have this type of structures.
(1) Group 1st Halides
ie NaI, KCl, RbI, RbF ( except Cs halides) .
(2) Group 2nd oxide MgO, CaO, BaO, SrO ( except BeO)
(3) Ammonium Halides ie NH4Cl
,NH4Br ,NH4I etc
(4) Silver Halides ie AgF, AgCl,
AgBr ,( except AgI)
(5) Other examples , TiO ,FeO,
NiO etc
Note: Ferrous oxide also has sodium chloride, types structure in which O-2
ions are arranged in ccp and Fe+2 ions occupy octahedral ions. However,
this oxide is always non – Stoichiometric and has the composition Fe0.95 O It can be explained on the assumption that some of the Fe+2
ion are replaced by 2/3rd as many Fe+3 ions in the
octahedral voids.
