In a mixed solvent of methanol and water, o-hydroxyacetophenone thiosemicarbazone (L = C9H11N3OS) and vanadyl acetylacetonate VO (acac) 2 are reacted in the presence of sodium acetate to obtain a novel two-dimensional layered supramolecule The complex was characterized by FTIR and X-ray single crystal diffraction. The crystal belongs to triclinic system, P1-space group, unit cell parameter Are as follows: a = 0.780 87 (9) nm, b = 1.232 82 (13) nm, c = 1.337 4 (2) nm, α = 108.708 (8) °, β = 91.299 ), V = 1.151 7 (3) nm3, Z = 2, Dc = 1.420 g.cm-3, μ = 0.565 mm-1, F (000) = 514, R1 = 0.051 6, ωR2 = 1.102 2. The vanadium center is a nearly ideal octahedral configuration of hexacoordination, forming a unique two-dimensional layered supramolecular structure through hydrogen bonding and π-π interaction.Furthermore, the fluorescence properties and thermal stability of the complex have been studied.CCDC : 764394.
