Two rare earth complexes of Ts-β-AlaH with the formula of [Ln2(H2O)4(Ts-β-AlaH)6]n·4nH2O (where Ln =Nd(1), Gd(2); Ts-β-AlaH = N-p-tolylsulfonyl-β-Alanine) have been synthesized and characterized by elemental analysis, IR,and X-ray diffraction. The results show that the two complexes are isostructural. They crystallize in a monoclinic system with P21/n space group. Crystal data for 1: a = 0.95149(19) nm, b = 1.9012(4) nm, c = 2.2863(5) nm, β= 100.37(3)°, Z = 4,Dc = 1.509 mg/cm3, F(000) = 1880, R1 = 0.0560, wR2 = 0.1564 [Ⅰ＞ 2σ(Ⅰ)]; for 2: a = 0.9495(2) nm, b = 1.9037(4) nm, c =2.2987(5) nm, β= 99.87(3)°, Z = 4, Dc= 1.541 mg/cm3, F(000) = 1916, R1 = 0.0515, wR2= 0.1566 [Ⅰ＞2σ (Ⅰ)]. The two complexes are one-dimensional chains and the coordination number of the Nd3+ or Gd 3+ ion is nine.
