Kompleksni spojevi molibdena(VI) s makrocikličkim imino-ligandima

Imine compounds prepared by the reaction of 3-acetyl-6-methyl-2H-pyran-2, 4(3H)-dione (DHA) with various amines are potentially polidentate ligands. DHA is used as antimicrobial and antifungal agent in pharmaceuticals and cosmetics [1]. It is comercially available compound obtained by the autocondensation of ethyl acetoacetate. As part of our research on molybdenum complexes with biologically important organic compounds [2], we have prepared several new molybdenum(VI) complexes with these imine ligands. The complexes have been characterized by chemical and thermogravimetric (TG) analysis, X-ray powder diffraction, IR, 1H NMR, 13C NMR studies and, in some cases, single crystal X-ray diffraction method.
