A pyridine-diimine compound N,N'-[pyridine-2,6-diyldi(E)methylylidene]bis(4-chloroaniline) is synthesised by a Schiff base condensation of 2,6-diformylpyridine with 4-chloroaniline in methanol and characterised by spectroscopic and analytical techniques. The molecular structure of the compound is determined by the single crystal X-ray diffraction study. The compound crystallizes in the monoclinic crystal system, I2/c space group with unit cell parameters a = 7.0843(12) , b = 6.1909(11) , c = 36.262(6) , beta = 91.576(3)A degrees, V = 1589.8(5) (3) and Z = 4. There is an intermolecular hydrogen bonding in the molecule resulting in a 1D hydrogen bonding chain and these hydrogen bonding chains are linked by ClaEuro broken vertical bar HC(aromatic) interactions forming a 2D network. Crystal packing of the compound is determined by ClaEuro broken vertical bar HC and pi-pi interactions. In the fluorescence emission spectra in CH3CN, DMF, DMSO and EtOH, the compound shows only one emission maximum.
