Complexes of V(V), Co(II), Ni(II), Cu(II), Pd(II) and Cd(II) with (MPMPB) have been investigated in solution using Potentiometric and spectrophotometric methods. The composition of the complexes was determined to be 1:1 and/or 1:2 (M: L), the optimum conditions favouring the formation of the coloured complexes were studied extensively; protonation constants and their stability constants of the complexes were calculated. Adherence to Beer\'s law was observed for the µgmL-1 concentration range. Moreover, the solid complexes have been characterized by elemental analyses, electronic spectra, thermal method (TGA and DTA), IR and X-ray powder diffraction. The antimicrobial activities of the ligands and their complexes have been studied by screening the compounds against the bacteria S. marcescens (-ve), P. eruginosa (-ve), E. coli (-ve), S. aurous (+ve), B. cereus (+ve) and M. luteus and also the fungi C. albicans (-ve), G. Candidum (-ve), A. flavus (+ve), F.oxysporium (-ve), S. brevicaulis (+ve) and T.rubrum and results have been compared with the standard drug,
