A novel palladium(Ⅱ) complex [Pd(H2bpdc)Ala]Cl·3H2O (where H2bpdc is 2,2′-bipyridine-3,3′-dicar- boxylic acid and Ala is L-alanine) has been synthesized and characterized by IR spectra and elemental analysis. The crystal structure of the complex has been determined by single-crystal X-ray diffraction analysis. It crystallizes in triclinic system, space group P1 with a=0.685 5(2) nm, b=0.988 4(4) nm, c=1.349 6(4) nm, α=98.375(8)°, β= 97.900(15)°, γ=90.118(15)°, V=0.895 9(5) nm3, Z=2. In the molecule, Pd(Ⅱ) atom is four-coordinated and located at the centre of a planar quadrangle. The complex is assembled via intramolecular π-π stacking interactions and hydrogen bonds, which forms 2D network. The cyclic voltammetric behavior of the complex was also investigated.
