Figure 5

The Lewis acid/base interaction matrix.

The six types of Lewis acid and four types of Lewis base interact to give 24 distinct types of Lewis acid/base complex and associated complexation chemistry.

The matrix has many properties, for example: most basic reagents, such as sodium hydroxide, calcium carbonate and methyl lithium, are Type 7 complexes; pi/pi interactions—including Diels-Alder cycloaddition chemistry—is associated with Type 20 complexation; classical inorganic coordination chemistry is associated with Type 23 complexation and Type 24 complexation includes all pi/transition metal chemistry. Congeneric series, planars and volumes are always found within cells and never straddling cells. The extensive properties of the matrix are discussed in ref. 21.
