The Molecular and Electronic Structure of [ReOX3(AsPh3)(OAsPh3)] Complexes (X = Cl, Br)

“…Oxo-complexes are catalysts for organic reactions, models for active sites in heterogeneous processes and very useful starting reagents in coordination chemistry [1][2][3][4][5][6][7][8][9][10][11][12][13][14]. They also appear to be involved in the catalytic cycles of a variety of metalloenzymes, for instance those of cytochrome P-450, nitrogenase and xanthine oxidase [15][16][17].…”

Synthesis, characterization and structural investigation of new rhenium-oxo complexes containing bidentate phosphine ligands: an exploration of chirality and conformation in chelate rings of small and large bite angle ligands

“…3,4 The more recent application of rhenium complexes as radiopharmaceutical agents, [5][6][7][8] as well as their role as models for technetium complexes, which are also extensively used as radiopharmaceuticals, 9,10 has given rise to a significant area of research. Oxorhenium(V) complexes of the type [ReOX 3 L 2 ] (X = halogen; L = triaryl or alkyl phosphine, arsine or stibine ligands) are versatile precursors in the synthesis of a wide variety of rhenium complexes [11][12][13][14][15][16] and also display activity as oxygen transfer agents. [17][18][19][20][21][22][23][24][25][26] Organophosphorus compounds continue to gain in popularity as ligands in synthetic inorganic chemistry since, by varying the substituents on the phosphorus, the chemical behavior of both the ligand and the resultant complex can be altered.…”
