Popis: IF a warm alcoholic solution of cupric chloride is treated with diphenyl methyl arsine and allowed to stand overnight, two crystalline species (brown and blue) of identical composition (Cu2(Ph2MeAs)3Cl3) are deposited. The separation of these two substances has already been described1. At that time the evidence put forward was insufficient to show whether the two compounds were really isomeric or not. Recently, however, it has been found that the two compounds are appreciably soluble in nitro-benzene, in which solvent the molecular weights of the two are of the same order (brown 878, blue 786). One form is therefore not a polymer of the other. Furthermore, these values, although somewhat lower than the theoretical (986), support the view that each form is binuclear.
