Bimetallic paddlewheel complexes derived from imides of ( S )- tert -leucine adopt 'chiral crown' configurations in which the four imide groups are projected in a chiral arrangement on one face, and the four tert -butyl groups are projected on the opposite face. In this contribution, the generality of the chiral crown conformation is examined through crystallographic studies where the metal and the nature of the chiral ligands are altered. Based upon these observations, a model is proposed to explain the factors which create bias for the chiral crown configuration. The generality of the chiral crown conformation is examined by varying the metal and the chiral ligands in crystalline complexes. Factors that bias for the chiral crown conformation are explained.
