Synthesis and structure of novel bipyridine type ligand.L L= N,Ń-bis-pyridin-2-ylmethylene-naphthalene-1,5-diamine

A novel bipyridine-type linking ligand L ((2-py)-CH==N-C10H6-N==CH-(2-py)) was prepared by the Schiff-base condensation and fully characterized by sprctroscopicmethods and single-crystal X-ray diffraction.The unit cell parameters are : space group P21/c with a = 4.8666(8) Å, b = 16.780(3) Å, c =10.0559(16)Å, α = 90o, β =90.504(3)º, γ = 90o, and Z = 2. These parameters suggested a monoclinic unit cell.
