| Abstract: A complex [NaNd(BDOA)2(H2O)2]·4H2O (BDOA=1,2-phenylenedioxydiacetate ) has been prepared by solvent method. The title complex was characterized by X-ray single-crystal diffraction. The complex belongs to triclinic system with space group P1, a=0.874 090(10) nm, b=1.230 49(2) nm, c=1.270 79(2) nm, α=76.039 0(10)°, β=78.285 0(10)°, γ=84.489 0(10)°, V=1.297 21(3) nm3, Z=2, F(000)=726, R1=0.023 4, wR2=0.056 7. Two kinds of centers metal ions Nd3+ and Na+ ions are in the complex. Metal ions are connected into a 1D chain through water oxygen atoms, tridentate caboxylate oxygen and bidentate caboxylate oxygen atoms. Each Nd3+ ion is coordinated by four caboxylate oxygen atoms，four ether oxygen atoms from two BDOA ligands and two water molecules. The Na+ is coordinated by four carboxylate oxygen atoms and two water molecules. The adjacent 1D chains are connected by hydrogen bonds and π-π stacking interactions into 3D supramolecular structure.
