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.
