Abstract
It is shown that the progressive substitution of a small amount of Pd and Pt by Ph in Pd3V and Pt3V whose ground state is the DO22 structure , or the substitution of V by Ti in Pt3V, stabilizes a few simple long period structures and finally the L1(2) structure. This occurs for an electron per atom ratio about 8.6, in full agreement with accurate el ectronic structure calculations.
