Bridging superstructures added to small azamacrocycles, through the accompanying additional topological constraint, enhance the characteristic that makes azamacrocycles indispensable ligands for transition metal coordination including biomimetic chemistry: high complex stability. This review begins by briefly revisiting the coordination chemistry concepts leading to this advantage over less top...

Over the last 2 decades, the rapid development of new synthetic routes for the preparation of expanded porphyrin macrocycles has allowed for the exploration of a new frontier consisting of "porphyrin-like" coordination chemistry. In this Account, we summarize our exploratory forays into the still relatively poorly explored area of oligopyrrolic macrocycle metalation chemistry. Specifically, we ...

Among the characteristic features of the coordination chemistry of ruthenium, which are manifested by complexes containing a considerable range of ligands, are the propensities for intraand intermolecular metallation of arenes and for the formation of polyhydride complexes. Some aspects of this coordination chemistry are discussed, including the roles of ruthenium polyhydride complexes in catal...

In this paper, the inclusion complexation between host and guest in cyclodextrin (CD) chemistry is care fully compared with the coordination interaction between central ion (Mx+) and ligands in coordination chemistry. In viewof the importanceof the concept of the coordinationnumber (CN)ofMx+ in coordination compounds, the inclusion number (IN) is first defined to evaluate the nature of inclusio...

Chelation therapy is one of the most appreciated methods in the treatment of metal induced disease predisposition. Coordination chemistry provides a way to understand metal association in biological structures. In this work we have implemented coordination chemistry to study nickel coordination due to its high impact in industrial usage and thereby health consequences. This paper reports the an...
