Double rock-salt-type layers

Incommensurability comes from the mismatch between periodicities of the two entities, along one direction. Their general formulation is defined and now well admitted as [(MQ)m]i+j(TQ2) , with m =, 1.5, 2 and n = 1, 2, 3, the 1 + X valne being related to the incommensnrability. Such a formulation clearly indicates the composite nature of the compoimds, with (MQ) and (TQ2) sublattices that are of rock salt type structure for (MQ) (double-layer-thick for w = 1, or three-layer-thick for m = 1.5) and of Cdl2 type stmctnre for (TQ2) (T = Ti, V, Cr, i.e. an octahedral coordination) or NbS2 (T = Nb, Ta, i.e. a trigonal prismatic coordination)... [Pg.722]
