The effects of chlorine atoms on the fundamental frequencies of the s-triazine ring are discussed and the vibrational assignments in the region 1600–700 cm−1 are extended. The variation in the position of the C3N3-ring bending mode in the region near 810 cm−1 is discussed.

Paramagnetic adducts of the nickel(11) chelates of the fluorinated monothio-β-diketones RC(SH)=CHCOCF3 (R = β-naphthyl, p-ClC6H4, m-ClC6H4, m-BrC6H4, m-MeC6H4, 3,4-Cl2C6H3) have been obtained with pyridine, y-picoline, 2,2'-bipyridyl, and 1,l0-phenanthroline. They are of the type NiL2(base)2 (L = RCS=CHCOCF3; base = py, γpic, �bpy, �phen). With 2,2',2"-terpyridyl two types of adduct were isolated: (a) mononuclear NiL2(trpy) and (b) trinuclear Ni3L6(trpy)2. The infrared spectra of all the adducts display v(C-O) in the range 1552-1580 cm-l; this band is characteristic of a bidentate monothio-β-diketonato ligand. The spectra of the mononuclear terpyridyl adducts display in addition a v(C=O) band at c. 1650 cm-1, indicating that one carbonyl group is not coordinated.

Triphenylbismuth(V) acid derivatives of the type, Ph3BiX2, where X = halide, nitrate, cyanate, acetate, haloacetate, or cyanoacetate have been prepared. Infrared spectra (4000 to 200 cm−1 region), electrical conductances, and molecular weights of these compounds have been studied to elucidate their structural features and chemical constitution. The molecular weight and conductance data show that these compounds behave as molecular species in benzene or nitromethane. The infrared spectroscopic results also indicate non-ionic five-coordinate structures. Bi—X stretching frequencies have been assigned for the difluoride, dichloride, dinitrate, dicyanate, and diacetate. These frequencies occur in the region 410–240 cm−1.
