Two tricarbonyl complexes of rhenium(I) and manganese(I) coordinated by the ligand 2‐{[2‐(1 H ‐imidazol‐4‐yl)ethyl]iminomethyl}‐5‐methylphenolate are reported, viz. fac ‐tricarbonyl(2‐{[2‐(1 H ‐imidazol‐4‐yl‐κ N 3 )ethyl]iminomethyl‐κ N }‐5‐methylphenolato‐κ O )rhenium(I) methanol monosolvate, [Re(C 16 H 14 N 3 O 4 )(CO) 3 ]·CH 3 OH, (I), and fac ‐tricarbonyl(2‐{[2‐(1 H ‐imidazol‐4‐yl‐κ N 3 )ethyl]iminomethyl‐κ N }‐5‐methylphenolato‐κ O )manganese(I), fac ‐[Mn(C 16 H 14 N 3 O 4 )(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.
