Abstract
The low-temperature reactions of aliphatic primary phosphines and phosphide s with E(NMe2)(3) (E=As, Sb) give cyclic anions of the type [(RP)(n)E](-). At higher temperatures Zintl compounds containing E-7(3-) anions are genera ted. In contrast, related reactions using aryl phosphines lead to the direc t formation of Zintl compounds even at low temperature. The reactions of al iphatic and aryl arsines follow a similar pattern to that of the correspond ing phosphines. The syntheses and X-ray structures of several complexes con taining [(RP)(n)E](-) (n=3 or 4) and E-7(3-) anions are reported.
