N2 - The complexes (C6F5)2TlX [X = MeCOCHCOMe (acac), CF3COCHCOMe (tfac), CF3COCHCOCF3 (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 (C_sup_2_/sup_ F5)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.
