Imines, either acyclic or macrocyclic but invariably multidentate, have a rich coordination chemistry that has been investigated at length. The 7r-accepting ability of imine donors results in the stabilization of lower oxidation states relative to their saturated amine analogs, and there exist many air-stable divalent imine complexes of Co, in contrast to amine relatives. The hexa-methyl-diene (52) has been the most intensively studied ligand of this class, particularly when complexed with Co. In addition, Co complexes of the dimethyl (53),295,296 tetramethyl (54),297 pentamethyl (55)298 and octamethyl (56)299 macrocyclic dienes are also known. In the presence of... 

Macrocyclic Schiff base compartmental ligands (750) (Robson-type ligands) derived from the [2 + 2] condensation of a 2,6-diformyl- or 2,6-diketo-substituted phenol and a diamine are very prominent in dinuclear Ni coordination chemistry.1901-1903 Particular interest lies in magnetic exchange interactions between the adjacent metal ions as well as in bioinorganic chemistry, where such dinuclear complexes have been proposed as synthetic analogues for bimetallosites. 

It is to be mentioned here that the coordination chemistry of macrocyclic ligands is covered in Volume 7. Therefore only selected systems having some direct relevance to the bioinorganic chemistry of copper will be discussed. Readers are recommended to consult review articles/ 3...

The development, synthesis, and the coordination chemistry of novel metal complexes with deep binding cavities have been described. It was demonstrated that the doubly deprotona-ted forms of the macrocycles (LR)2 support the formation of...

Some commonly used macrocycles. — The number in brackets indicates the size of the ring. The terms ane and ene denote saturated and unsaturated rings respectively. The number of ligating atoms is indicated by a subscript. A trivial name is often used (G. A. Melson in Coordination Chemistry of Macrocyclic Compounds, Ed. G. A. Melson, Plenum, New York, 1979, Chapter 1 Comprehensive Coordination Chemistry, Ed. G. Wilkinson, Pergamon, Oxford, 1987. Several chapters in Vol. 2 (Ligands)).
