... metal-metal bonding is present MX2 compounds either have layer structures (e.g TiS2, TiSe2, TiTe2, all CdI2 types) or structures containing diatomic ions (e.g FeS2 has S 22 units and so is formally ... E-E bonding are known (see Topic D5) CaC2 has C 22 ions (isoelectronic with N2) and reacts with water to give ethyne C2H2 On the other hand, KSi and CaSi2 are Zintl compounds with single-bonded ... polyanionic species (e.g P24− isoelectronic with S 22 in Sr2P2, and P73− in Na3P7), although the bonding is certainly not fully ionic Section F Chemistry of nonmetals F7 OXYGEN Key Notes The element...
