Chlorocuprate(II) and Chlorocobaltate(II) Salts of the Aminodiphenyl-phosphonitrileaminodiphenylphosphonium Ion
Two new compounds [NH2(C6H5)2PNP(C6H5)2NH2]2[CoCl4] and [NH2(C6H5)2PNP(C6H5)2NH2][CoCl4]CH2Cl2 have been isolated, and characterized by spectrometry, as examples of the general series of quaternary amine transition metal chloride salts. Three other compounds containing the same cations, with empirical formulae, CuP2N3C25H32OCl3 (1), CuP2N3C24H28Cl3 (2), and Cu3P4N6C50H64O2Cl8 (3) have been isolated and studied by spectrometry. The formulae [NH2(C6H5)2PNP(C6H5)2NH2]2[Cu2Cl6] and [NH2(C6H5)2PNP(C6H5)2NH2]2[Cu2Cl6]. 2CH3OH are proposed for (2) and (1) by comparison with the cobalt compounds, and interpretation of the electronic structure. These compounds were produced during attempts to synthesize mixed ring compounds of (PN) and (SN) units.
