| Abstract |
Reactions between 4 -phenyl-terpyridine (L) and several Zn(II) salts (p-toluenesulfonate, nitrate, trifluoromethane sulfonate or hexafluoroantimonate) led to the formation of the complexes [ZnL2](p-OSO2PhCH3)(2) (1), [ZnL2](NO3)(2) (2), [ZnL2](SO3CF3)(2) (3) and [ZnL2](SbF6)(2) (4), which were characterized by IR, H-1 NMR, elemental analysis, UV-vis spectroscopies and single crystal X-ray diffraction, along with their TG-DTA thermal and photoluminescent properties. The four compounds show mononuclear Zn(II) structures with hexacoordinated, irregular ZnN6 octahedron geometries. Their colours and photo luminescent properties have changed regularly depending on the counterions of the compounds. (C) 2017 Elsevier B.V. All rights reserved. |
