The majority of the compounds with Th/sub 3/P/sub 4/ structure exhibit nonmetallic and/or ferro- or antiferromagnetic properties. Superconductivity in the metallic chalcogenides La/sub 3/X/sub 4/ (X = S, Se, Te) which contain one excess valence electron per formula unit was discovered recently and fairly high values for the critical temperature T/sub c/were reported. The only nonmagnetic pnictides (thorium pnictides) are valence compounds and at least the phosphide and the arsenide are semiconductors. A large number of rare-earth pnictides of composition Ln/sub 4/Pn/sub 3/ adopt the anti-Th/sub 3/P/sub 4/ structure. Again most of these compounds order magnetically. Superconductivity was detected in the La-compounds below 1/sup 0/K Changes of T/sub c/ by substituting part of the cations or the anions are investigated and discussed.
