In view of the great biological, industrial and manifold applications of Sulfamethoxazole and imidazole complexes, there is a need for an understanding of the coordination possibilities of Sulfamethoxazole and imidazole. In this work, Cu(II),Co(II), Mn (II) and Zn(II) mixed-ligand complexes of sulpha drug (Sulfamethoxazole,L1) and imidazole (L2) in form of  (L1:M: L2)(1:1:2), have been prepared and their infrared and UV-Vis spectra have been investigated. The infrared spectra of the samples were recorded in the range 4000–400 cm_1 and their fundamental vibrational wave numbers were obtained. The electronic spectra of all the synthesized complexes were recorded on Spectro-UV-VIS double beam PC scanning spectrophotometer UVD 2960. In all the complexes, SMX behaves as a Tridentate ligand binding through two Ar-N atoms  and sulfonic oxygen while imidazole behaves as a monodentate with N donor atom. UV-Vis spectra suggests probable octahedral geometry for the complexes.
