Abstract
The hitherto unknown complexes, [M(CO)4(η2‐H2L)], [M=Cr; 1, Mo; 2, W; 3]; fac‐[Re(CO)3Br(η2‐H2L)], 4 and [(η5‐C5H5)Mn(CO)Br(η2‐H2L)], 5 have been synthesized by the photochemical reactions of VIB and VIIB metal carbonyls [M(CO)6] [M=Cr, Mo, W], Re(CO)5Br and (η5‐C5H5)Mn(CO)3 with chiral Schiff base N,N′‐bis‐(2‐hydroxynaphthalene‐1‐carbaldehydene)‐(1R,2R)‐(‐)‐diaminocyclohexane (H2L) in THF and characterized by elemental analyses, FTIR, 1H‐NMR and mass spectra. The spectroscopic studies show that H2L ligand is coordinated to the central metal as a bidentate ligand coordinating via its imine nitrogens (C˭N) in 1–5.
