Triphenyl Phosphine Oxide

Manganese(III) nitrate and its dinitrogen pentoxide "adduct" have been prepared by the reaction of N2O5 with MnF3. Infrared spectra and magnetic susceptibility measurements show these compounds to contain high-spin manganese(III) coordinated by nitrate groups and the "adduct" to be the nitronium salt, [NO2]+[Mn(NO3)4]−. The syntheses of complexes of Mn(NO3)3 with some organic ligands, e.g., 2,2′-bipyridyl, o-phenanthroline, acetonitrile, and triphenyl phosphine oxide are described.

Triphenyl Phosphine Oxide

The complexes (C6F5)2TlX [X = MeCOCHCOMe (acac), CF3COCHCOMe (tfac), CF8COCHCOCF3 (hfac), PhCOCHCOMe (bzac), PhCOCHCOPh (dbm), or quinolin-8- olate (oxinate or ox)], have been prepared by reactions between bromobis(pentafluorophenyl)thallium(III) and the appropriate sodium or thallous β-diketonates or sodium quinolin-8-olate, and react with equimolar amounts of 1,10-phenanthroline (phen) or 2,2?-bipyridyl (bipy) to give the complexes (C6F5)2- (phen or bipy)TlX (X = acac, tfac, or hfac), (C6F5)2(phen)TlX (X = bzac, dbm, or ox), but not (C6F5)2(bipy)TlX (X = bzac, dbm, or ox). On reaction with triphenyl- phosphine oxide or triphenylarsine oxide, the complexes (C6F5)2(Ph3PO or Ph3AsO)-TlX (X = acac, tfac, hfac, or dbm) and (C6F5)2Ph3AsOTl(ox) have been obtained. From conductance and molecular weight measurements and spectroscopic data, the complexes (C6F5)2TlX (except X = ox), (C6F5)2(Ph3PO or Ph3AsO)TlX, and (C6F5)2(phen or bipy)TlX, are considered to be monomeric with chelated β-diketonate or oxinate groups, and hence to contain four-, five-, and six-coordinate thallium respectively, whereas (C6F5)2Tl(ox) is considered to have an associated structure with bridging oxinate groups.
