Three new Mn(II) macrocyclic Schiff-base complexes have been prepared via cyclocondensation of 2,9-dicarboxaldehyde-1,10-phenanthroline and three linear tetradentateamines via a metal-templated reaction and coordination features have been examined. The complexes are18- and 19-membered hexaazamacrocycles, and incorporate a 1,10-phenanthroline unit as an integral part of their cyclic structure. All complexes have been characterized by a variety of methods such as IR, elementalanalysis, EI- Mass, and conductivity measurements Also the synthesized complexes were screened for their antibacterial activities against six bacterial strains and showed antibacterial effects.
