Coordination Chemistry of Bridged Transition Metal Complexes

Abstract

newline The preparation of bridged molecule-based magnetic materials to utilize as multidentate ligands newlineand linkers has shown importance in the bioinorganic field as these building blocks are good newlinecandidates to provide the directional assembly with controllable structure and physical properties. newlineThe development of new synthetic assemblies can yield compounds with a large spin, anisotropy, newlineand/or strong magnetic coupling. Bridged Transition Metal Complex systems offer a great advantage newlinefor achieving such control, through the substitution of various metal ions into a given structure type. newlineAs a result, a large number of bridged complexes with various structural types have been newlinesuccessfully synthesized. On the same theme, I attempted the synthesis of cyano-bridged complexes newlineand carboxylate-bridged complexes along with the structural, magnetic, and reactivity properties of newlinethese assemblies. newline This thesis has been divided into five chapters. Introductory Chapter 1 sets the stage for the newlinescope of the present investigation along with the primary aim of the work that has been carried out. newline Chapter 2 includes the review of selected ligands substantial to the work that has been newlinecarried out. Complexes prepared using these ligands along with various studies are also included. newlineThis chapter has been divided into six tables. The complexes prepared using these ligands are newlineincluded along with the various studies. The complexes are comprised of five tables, where Table newline2.1 outlines the discrete cyanide-bridged di-nuclear complexes whereas Table 2.2 outlines cyanide- newlinebridged tetra-nuclear coordination complexes, and Table 2.3 lists some more cyanide-bridged newlinecoordination complexes except di-nuclear and tetra-nuclear complexes along with the ligands used newlinein the study. Table 2.4 outlines the dimeric complexes of carboxylate bridged ligands, whereas newlineTable 2.5 outlines the tetrameric complexes of carboxylate bridged ligands.
