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.
报道了由配体2-{[2-(1H-咪唑-4-基)乙基]亚氨基甲基}-5-甲基苯酚盐配位的两种铼(I)和锰(I)的三羰基配合物，即面式-三羰基(2-{[2-(1H-咪唑-4-基-κN(3))乙基]亚氨基甲基-κN}-5-甲基苯酚根-κO)铼(I)甲醇单溶剂合物，[Re(C₁₆H₁₄N₃O₄)(CO)₃]·CH₃OH，(I)，和面式-三羰基(2-{[2-(1H-咪唑-4-基-κN(3))乙基]亚氨基甲基-κN}-5-甲基苯酚根-κO)锰(I)，面式-[Mn(C₁₆H₁₄N₃O₄)(CO)₃]，(II)，它们在扭曲的八面体环境中呈现面式配位。(I)的晶体结构通过O-H···O、N-H···O和C-H···O氢键相互作用得以稳定，而(II)的晶体结构仅通过N-H···O氢键相互作用得以稳定。这些相互作用导致两种结构都形成二维网络和π-π堆积。
