Abstract
Two tricarbonyl complexes of rhenium(I) and manganese(I) coordinated by the ligand 2-{[2-(1H-imidazol-4-yl)ethyl]iminomethyl}-5-methylphenolate are reported, viz. fac-tricarbonyl(2-{[2-(1H-imidazol-4-yl-κN(3))ethyl]iminomethyl-κN}-5-methylphenolato-κO)rhenium(I) methanol monosolvate, [Re(C16H14N3O4)(CO)3]·CH3OH, (I), and fac-tricarbonyl(2-{[2-(1H-imidazol-4-yl-κN(3))ethyl]iminomethyl-κN}-5-methylphenolato-κO)manganese(I), fac-[Mn(C16H14N3O4)(CO)3], (II), display facial coordination in a distorted octahedral environment. The crystal structure of (I) is stabilized by O-H···O, N-H···O and C-H···O hydrogen-bond interactions, while that of (II) is stabilized by N-H...O hydrogen-bond interactions only. These interactions result in two-dimensional networks and π-π stacking for both structures.
