Abstract

Segments of the basic structures BaAl4, AlB2, W, Po, Cu3Au, CaF2 or hybrids obtained combining two segments of these types are used with the mechanism of intergrowth to describe nine linear structures of binary and ternary intermetallic compounds formed by rare earth or alkaline earth metals. Such a representation allows to display relationship among the structures. All examined compounds with one exception contain AlB2 fragments, that means rare earth or alkaline earth face-sharing trigonal prisms centred by the small atoms. Depending on the segments between which the AlB2 fragment is comprised, the atoms centring the prisms show a different behaviour in their waist contacts.
