Phosphorus-arsenic substitution can help to stabilize peculiar compounds that do not exist as binary phases. So far, a binary arsenide W5AS4 has not been reported. Nevertheless, W5As2.5Pi.5 can be synthesized. It adopts the tetragonal Ti5Te4 type, as M05AS4 does. Most likely radii criteria are responsible for the stability range of this pnictide which contains one-dimensional chains of vertex-shared We clusters.

The polarizability, first and second hyperpolarizabilities of stoichiometric gallium arsenide clusters Ga As ( = 2-9) has been calculated using the finite field procedure combined with HF and MP2 energies. The first hyperpolarizability has been shown to be much more sensitive to geometrical features than the second hyperpolarizability. The evolutions with the cluster size of the average polarizability per atom and of the polarizability anisotropy have been assessed and compared to the Clausius-Mossoti bulk limit.
