Synthesis, Crystal Structure and Characterizations of Zn (II) Complex with pmtpo and NCS−(Pmtpo = 2-(2-pyridylmethylthio)-5-(4-pyridyl)-1,3,4-oxadiazole)

The reaction of zinc(II) sulfate with ligand pmtpo and KSCN gave rise to a supramolecular complex, [Zn(pmtpo)2(NCS)2], (Pmtpo = 2-(2-pyridylmethylthio)-5-(4-pyridyl)-1,3,4-oxadiazole), which was characterized by X-ray diffraction analysis, UV and IR spectra. This complex is crystallized in a monoclinic space group C2/c and in the complex crystal structure, the center Zn(II) ion has a tetrahedron coordination environment. The structure is extended by weak (4-pyridyl)C–H…SCN− hydrogen bonding and two-sorted weak π −π packing interactions. The fluorescent property and thermal stability of the complex are researched.
