The Structural and Magnetic Properties of First‐Row Transition‐Metal Dimers Containing Hydroxo, Substituted Hydroxo, and Halogen Bridges

Some complexes of the chlorides and bromides of manganese(II), iron(II), cobalt(II), nickel(II) and copper(II) with nicotinamide and nicotinic acid have been prepared. These complexes have stoichiometryML
2X2 whereM is a metal ion,L is an organic ligand andX is a halide ion. Spectral and magnetic properties indicate that these compounds have octahedral polymeric structures. The decomposition of the complexes was studied by thermogravimetry and differential thermal analysis. In only one instance was a decomposition product of the formulaMLX2 obtained. Its structure was also octahedral.

The preparation and spectroscopic properties of some complexes formed between transition metal halides and substituted anilines

Complexes have been prepared between iron(II), copper(II), zinc(II), and cadmium(II) halides and pyridine, α-, β-, and γ-picoline, 2,6-lutidine, and 2,4,6-collidine. Where possible, structural types are identified. The present complexes are compared with similar compounds of chromium(II), manganese(II), cobalt(II), and nickel(II).

Pyridine complexes of iron(II), copper(II), zinc(II), and cadmium(II) halides

A series of pyridine, γ-picoline, and quinoline complexes have been prepared with manganese(II), cobalt(II), nickel(II), copper(II), and zinc(II) perchlorates and tetrafluoroborates. The pyridine and γ-picoline complexes have the general formula M(L)4(ClO4)2 or M(L)4(BF4)2. With quinoline, two series of complexes were prepared. The first had the formula MQ2(ClO4)2 and MQ2(BF4)2 and the second MQ2F(BF4). The ultraviolet and visible reflectance spectra, infrared spectra, and magnetic properties of these compounds have been measured and are discussed.
