A green chemistry route of synthesis using direct sunlight irradiation for the reactions of [M(CO)6] M = Cr, Mo or W with 2-[2-(methylaminoethyl)] pyridine (maepy) in THF. The reactions resulted in the formation of the oxo complex [Cr2(O)4(maepy)2] (1) and the tetracarbonyl complexes [Mo(CO)4(maepy)] (2) and [W(CO)4(maepy)] (3). The prepared complexes were characterized by elemental analysis, IR, NMR, mass spectrometry and magnetic measurement. The complexes (1–3) were further investigated by thermogravimetric technique (TG). The biological activity of maepy and complexes as antibacterial and antifungal reagents have been investigated.
