Photochemical Reactions of Metal Carbonyls [M(CO) 6 (M = Cr, Mo, W), Mn(CO) 3Cp ] With 4-Amino-3-Hydrazino-5-Mercapto-1,2,4-Triazole (AHMT) and 3-Amino-5-Mercapto-1,2,4-Triazole (AMT).

Four new complexes of M(CO)5(AHMT) [M = Mo(1), Cr (2), W (3)], and Mn(CO)3 (AHMT) (4), where AHMT is 4-amino-3-hydrazino-5-mercapto-1,2,4-triazole have been synthesized by the photochemical reactions of metal carbonyls M(CO)6 (M = Mo, Cr, W) and Mn(CO)3 Cp with AHMT (1–4). In addition four more new complexes of M(CO)5(AMT) [M = Mo(5), Cr (6), W (7)], and Mn(CO)3 (AHMT) (8), where AMT is 3-amino-5-mercapto-1,2,4-triazole (AMT), have been synthesized by the photochemical reactions of metal carbonyls M(CO)6 (M = Mo, Cr, W) and Mn(CO)3 Cp with AMT (5–8). The complexes have been characterized by elemental analysis, FT-IR, 1H and 13C-NMR spectroscopy. The spectroscopic studies show that AHMT complexes (1–3) and AMT complexes (5–7) behave as a monodentate ligand and coordinate via ring NH donor atom to the central metal atom in M(CO)5(AHMT) and M(CO)5(AMT) where M = Mo, Cr, W, and as a tridentate ligand coordinating via imine nitrogen donor atom, amino N donor atom, and ring NH donor atom in Mn(CO)3 (AHMT) and Mn(CO)3 (AMT).
