Abstract
The title compound, [Zn(pytpy)2][NO3]2·2H2O (pytpy = 4′-(4-pyridyl)-2,2′: 6′,2″-terpyridine), has been synthesized by the reaction of Zn(NO3)2∙6H2O with pytpy, and its crystal structure was determined by single-crystal X-ray diffraction. The crystal belongs to tetragonal space group P43 with a = 0.90873(8), b = 0.90873(8), c = 4.4741(6) nm, V = 3.6946(7) nm3, Z = 4, Dc = 1.521 g/cm-3, μ = 0.736 mm-1, F(000) = 1744, R = 0.0871, wR = 0.1302 for 5553 observed reflections with I > 2σ(I). X-ray analysis has revealed that the ZnII ion is surrounded by six N atoms from two pytpy ligands leading to a distorted octahedral geometry. In the crystal structure there are numerous strong intermolecular and intramolecular H-bonds and π-π interactions.
