Synthesis, structural studies and antimicrobial activities of manganese, nickel and copper complexes of two new tridentate 2‑formylpyridine thiosemicarbazone ligands

Two new thiosemicarbazone ligands and their manganese, nickel and copper complexes were prepared. Two complexes were studied by single crystal X-ray; a square planar nickel complex in which each nickel atom is tetracoordinated and a copper complex exists in two different geometries (square planar & square pyramidal).98
