Studies of Tetrakis (Pyridine Base) Nickel (II) Perchlorate and Bisperchloratotetrakis (Pyridine Base) Nickel (II) Complexes

The stereochemistry of nickel (II) compounds has been one of the most active and controversial fields of research in inorganic chemistry during the last 10 years. The multitude of colorful nickel compounds has intrigued chemists for a much longer time, but only in relatively recent years have such tools as visible and infrared absorptiometry, group theory and quantum mechanics, magnetic measurements, x-ray studies, and conductance measurements been brought to bear effectively to unravel the questions on stereochemistry in metal complexes.
