X-ray crystal structure determination of one manganese(II) complex %V 28 %X Three new branched hexadentate amines (N(6)), 3,6-bis(2-pyridylmethyl)-3,6-diazaoctane-1,8-diamine (1), 3,7-bis(2-pyridylmethyl)-3,7-diazanonane-1,9-diamine (2) and 3,8-bis(2-pyridylmethyl)-3,8-diazadecane-1,10-diamine (3) have been synthesized. Subsequently, three novel Schiff base macrocyclic complexes containing a phenanthroline and two 2-pyridylmethyl pendant arms have been prepared by template 1+1 cyclocondensation of 2,9-dicarboxaldehyde-1,10-phenanthroline and the branched hexadentate amines (1-3), in the presence of Mn(II) in methanol. These complexes have ligands with 18-, 19-and 20-membered hexaaza macrocycles and two 2-pyridylmethyl pendant arms (L(1), L(2) and L(3), respectively). All the complexes have been characterized by elemental analysis and IR spectroscopy. The crystal structure of MnL(1)(ClO(4))(2) center dot 3CH(3)CN was determined and indicates that in the solid state the complex adopts a slightly distorted hexagonal bipyramidal geometry with the Mn(II) ion located within a hexaaza macrocycle with the two 2-pyridylmethyl pendant arms coordinating in axial positions.
