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 a = 19.698（7）, b = 21.045（7） c = 9.062（3） A, Z = 4, V= 3757（2） A3, C40H46N206PdS2, Mr = 821.31, D, = 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...zr 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.
