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).
