Interaction of [MoO(acac)] with internally functionalized oximes like HON=C(CH)Ar (Ar = CHS, CHO or CHN) and Schiff's Bases derived from β - diketones like HOC(R)CHC(R')=NCH (R = R' = CH or CH; R = CH and R' = CH) led to the formation of yellow dioxomolybdenum(VI) complexes of the type [MoO{ON=C(CH)Ar}] and [MoO{OC(R)CHC(R')=NCH}]. Oximes were synthesized by green methodology. The newly synthesized complexes were characterized on basis of elemental analysis and various spectral findings. Anticandidal activity of [MoO{ON=C(CH)CHN}] clearly reveals that the complex is biologically active against fungal diseases.
