Abstract
The azido-bridged binuclear manganese complex [{Mn(0.5H2O)(0.5N3)(tptz)(NO3)}2(μ1,3-N3)] [tptz=2,4,6-tris(2-pyridyl)-1,3,5-triazine] has been synthesised and structurally characterised. Two [Mn(0.5H2O)(0.5N3)(tptz)(NO3)] units are bridged by the end-to-end (EE) azide ligand. The Mn atoms are seven coordinated, with the five equatorial positions occupied by three N atoms of the tptz ligands and two O atoms of the nitrate ion and the two axial positions are coordinated by the N atom of the bridge azide ligand and the N atom of the disordered terminal azide ligand or the O atom of a disordered solvent water molecule, respectively. Magnetic susceptibility investigation shows antiferromagnetic coupling between the adjacent Mn(II) ions bridged by the azide ligands.
