초록/해제  
요약The series of heterometallic extended metal atom chains (HEMAC) complexes of the type M≣M-M' (M = Cr, Mo, W; M' = Cr, Mn, Fe, Co, Ni) supported by the equatorial ligand 2,2-dipyridylamide (dpa) has been systematically investigated over the last 20 years. Chapter 1 of this thesis introduces the idea of heteromultimetallic complexes within the framework of ligand field theory and outlines the electronic structure of typical HEMAC complexes. Chapter 2 of this thesis explores how varying the identities of the bimetallic "metalloligand" and the first-row transition metal within the asymmetric HEMAC framework causes a variety of changes in the electronic structure of the molecule. This work investigates the interactions of the first-row transition metal with the W≣W metalloligand, especially in comparison to the Cr≣Cr and Mo≣Mo analogues. Chapter 3 details the some of the recent progress into the synthetic exploration of using cyclic imides as equatorial ligands in [Mo2]4+ paddle wheel structures. Chapter 4 characterizes the magnetic properties of two Ni compounds that are models of dioxygenases. Upon oxygen exposure, neither compound performs the dioxygenase reaction as intended, and the resulting compounds are magnetically characterized as well. Chapter 5 reports crystal structures of three different compounds designed to be second generation catalysts for ammonia oxidation. Chapter 6 investigates the magnetic properties of a series of two-coordinate transition metal compounds and their slow magnetic relaxation. Appendix 1 discusses the Mossbauer spectra of a pair of heterometallic coordination isomers.
