Abstract
The reported tetranuclear zinc(II) complex [Zn4(HL)4](NO3)4 .2H2O(H2L=1,5-bis(1-(pyridin-2- yl)ethylidene)carbonohydrazide) has been prepared by mixing a methanol solution of Zinc nitrate salt and a methanol solution of H2L in 1:1 molar ratio. The suitablemonocrystalsafforded wereanalysedby X-ray diffraction. The title compound crystallizes in the tetragonal space group I41/a with the following unit cell parameters: a = 14.0254(2) Å, b = 14.0254(2) Å, c = 35.7967(8) Å, α = 94.610(4)°, V = 7041.6(3) Å3 , Z = 4, R1 = 0.048 and wR2 = 0.136. The structuresare[2x2] square grids of tetramers units in whichthe metal ions are joined in pairs by the oxygen atom of the deprotonated hydrazono moiety in μ2-mode.Each Zn(II) ion is in a distorted octahedral environment. The supramolecular structuresare consolidated by multiple hydrogen bonds.The luminescence properties of the Schiff bases and his tetranuclearZn(II) complex have been examined. The results of the measurements indicate that the complex exhibited higher luminescence intensity than the free Schiff base ligand.
