A series of Mn(II) macrocyclic Schiff-base complexes [MnLnCl]+ (n = 1–4) have been prepared via the Mn(II) templated [1+1] cyclocondensation of 2,6-diacetylpyridine or 2,6-pyridinedicarbaldehyde with the symmetrical 1,4-bis(3-aminopropyl)piperazine or the novel asymmetrical N,N′(2-aminoethyl)(3-aminopropyl)piperazine linear amines containing piperazine moiety. The complexes have been characterized by elemental analyses, IR, FAB-MS, magnetic studies and conductivity measurements. The crystal structure of [MnL2(CH3OH)Cl](ClO4) and [MnL4Cl](PF6) complexes have also been determined showing the metal ion in a N4OCl pentagonal bipyramidal or N4Cl highly distorted octahedral geometry, respectively.
