Through a variation in the aryl substituents of the formamidinate ligand, a variety of dirhenium compounds has been synthesized with [XArNC(H)NArX]- where Ar is a substituted C6H5 or C6H4 aryl ring and X is p-MeO (1), H (3), m-MeO (4), p-Cl (5), m-Cl (6), m-CF3 (7), p-CF3 (8), 3,4-Cl2 (9), and 3,5-Cl2 (10a, 10b). UV/Vis and NMR spectroscopy and electrochemical data for 1 and 3-10 have been obtained. X-ray crystallographic analysis of Re2Cl2(μ-form)4 with four different diarylformamidinate ligands and one analog with two different interstitial solvents are presented; Re2Cl2(p-MeOC6H4)NCHN(p-MeOC6H4)]4 (1), Re2Cl2[m-MeOC6H4)NCHN(m-MeOC6H4)]4·2 CH2Cl2 (4), Re2Cl2[(3,4- Cl2C6H3)NCHN(3,4-Cl2C6H3)]4·2 CH2Cl2 (9), Re2Cl2[(3,5- Cl2C6H3)NCHN(3,5-Cl2C6H3)]4·4 CH2Cl2 (10a), and Re2Cl2[(3,5- Cl2C6H3)NCHN(3,5-Cl2C6H3)]4·OC4H8 (10b).
