4,4'-Bis[N-phenylsalicylaldimine-5)azo] biphenyl and its polychelates with Cr^III, MO^III, Fe^III, Ti^III VO^II, Zr^IV, Th^III and UO^II₂ have been prepared. The ligand acts as bisbidentate molecule coordinating through phenolic O and azomethine N atoms. The thermal data have been analyzed. The d.c. electrical conductivity data reveal semiconducting nature of the polychelates. All the polychelates and ligand have been screened for their antimicrobial activity.
