14-membered tetraaza macrocyclic ligand and its solid complexes of Cr(III) and Mn(II) have been synthesized and characterized by elemental analysis, conductometry, magnetic susceptibility, UV–visible, FTIR, 1H NMR spectra, powder X-ray diffraction and thermal analysis. From the microanalytical data, the stoichiometry of the complexes has been found to be 1:1 (metal:ligand) ratio. The TGA-DTA data suggest Cr(III) complex having one ionic nitrate ion, one water molecule and two coordinated nitrate ions and Mn(II) complex having one ionic water molecule and two coordinated chloride ions. The X-ray diffraction data suggest orthorhombic crystal system for Cr(III) and monoclinic crystal system for Mn(II) complexes.
