The mass spectra of several partially fluorinated P-diketonatochromium(iii) complexes have been determined and discussed. Hydroxyhexafluoro-isobutyric acid, H0C(CF3)2C02H (34), acts as a bidentate ligand and forms a tris-octahedral complex with chromium(iii). A new ligand, hydroxy-methylenenorcamphor (61) (HL) has been synthesized and CrL3 has been prepared and characterized. ... 

Triethanolamine complexes of chromium(iii) have been reported and characterized in i.r. spectra and thermal-decomposition studies. The chromium(iii) nitrilotriacetato-complex [CrL(H20)2] [L = N(CH2C02)3 ] complexes with thallium(iii) to give [ CrL3(0H)(H20) gTl] with a formation constant of 9 3 X 10 at 25 The hydrolysis and dimerization of [CrLlOHljV ... 

Iodine is determined by igniting a sample in air with the full flame of a Bunsen burner and comparing the weight of the chromium(III) oxide produced with the initial weight of the sample. Chromium is determined in the usual manner by fusing the oxide with sodium peroxide and measuring the quantity of chromate ion produced. Anal. Calcd. for Crl3 Cr, 12.02 I, 87.98. Found Cr, 12.03, 11.73 I, 85.47, 87.65. 

Two studies of the quenching of excited chromium(iii) complexes by Fe + have appeared. Rates correlate with redox potentials of the Cr ii complex, and this is the main, though not the only reason for assigning an electron- [CrL3] + + Fe2+ [CrL3] + + Fe + (81)...
