A novel 4′-(4-(diphenylamino)thienyl)-2,2′:6′,2′′-terpyridine ligand (L) based on thiophene and its LZnX2 complexes (X = Cl, Br, I, SCN) was designed, synthesized and characterized by elemental analysis, far-IR, MALDI-TOF-MS, and single crystal X-ray diffraction analysis. Structural studies revealed that the central zinc(II) atom adopted a distorted trigonal bipyramidal coordination model. However
