摘要A novel palladium(II) complex [(TMEDA)Pd(anca)2]•2DMSO (1, TMEDA = N,N,N',N'-tetramethylethylethylenediamine, anca = anthracene-9-carboxylic acid) was synthesized and characterized by single-crystal X-ray diffraction, 1H NMR, UV-Vis and fluorescence spectroscopy. The cell belongs to orthorhombic Aba2 space group with α = 19.698(7), b = 21.045(7) c = 9.062(3) Å, Z = 4, V = 3757(2) Å3, C40H46N2O6PdS2, Mr = 821.31, Dc = 1.452 g/cm3, F(000) = 1704, the final R = 0.0272, wR = 0.0667 and GOOF = 0.999. Complex 1 exhibits an interesting distorted clip-shaped molecular configuration which is stabilized by intramolecular C-H···O hydrogen bonds. The cells are packed into a 3D supramolecular structure based on the intermolecular C-H···π interactions which further construct the tubular channels serving as guest molecular channels to include the DMSO solvent molecules inside. Furthermore, the spectroscopic properties of 1 were also investigated.
