A dinuclear manganese macrocyclic complex with functional pendant arms, [Mn 2 (II)HL 2 ](ClO 4 ), has been prepared by the cyclocondensation of sodium 2,6-diformyl-4-methylphenolate with N,N-bis(2-aminoethyl)-N-(2-hydroxybenzyl)amine and subsequent transmetallation of Mn(II)(ClO 4 ) 2 . In the molec
## Abstract Two unsymmetrical tetradentate __aza__βmacrocycles with side arms attached to the N~sp~^3^ atoms, L^1^ and L^2^, as well as their complexes with different metal cations were synthesized and characterized by EA, UV, IR, ^1^H NMR and MS spectra. Both the two ligands can efficiently transp
