The next manganese complex to be considered is that with the Schiff base ligand shown in Scheme 6. 

Manganese(V) complexes of the Schiff base ligand salen and its derivatives have been the focus of intense study. These complexes have one additional ligand, either an 0x0, 0 , or a nitrido, group and much of the interest arises because these oxygen or nitrogen atoms are readily... 

Most of the polydentate ligands that stabilize manganese(III) are Schiff bases. In this section, complexes containing various polydentate ligands are summarized (see (Figures 3, 18 and 19) for... 

There are only trinuclear and tetranuclear manganese(III) complexes reported with hexadentate Schiff base ligands. Two such hexadentate ligands, bamen and Saltren (Figure 19), form unique core structures. 

A high-spin manganese(II) complex of the sulfur containing, potentially pentadentate Schiff base derivative (218) has been reported.

One of the earliest Schiff base macrocycles to exhibit a haemocyanine-like structure was the copper(II) perchlorate complex of 5.5 which binds readily to azide or hydroxide.8 The azide complex exhibits two square pyramidal copper binding domains with the basal plane occupied by one pyridyl nitrogen atom and two imine functionalities as well as a terminal azide ligand. The apices of the two pyramidal coordination polyhedra are linked by a single bridging azide anion. Continuing the biomimetic theme, manganese (II) cascade complexes of the unsymmetrical 5.6 have...
