✦ Synopsis

Dichlorobis(4-methylbenzenamine) cobalt(II), nickel(II), and copper(II) were synthesized individually via direct solid-solid reactions between 4-methylbenzenamine and CoCl 2 • 6H 2 O, NiCl 2 • 6H 2 O, and CuCl 2 • 2H 2 O at 20°C and were characterized by spectral studies. Interesting phenomena of the color change and evidently different formation rates of these reactions were observed when performed at 0°C. Furthermore, the concept of ''inert'' and ''labile'' complexes is applied for the first time to explain the rates of the substitution reactions in the solid state.
