Abstract: The complex of (La(DAPSC)(NO3)3 H2O) · H2O was prepared. Its crystal data are: triclinic, space group P1, a =8.736(1), b = 12.108(3), c =12.412(3)Å, α=110.35(2)°, β =94.88(1)°, γ = 95.35(2)°, v =1215.78(Å3, Z =2.It was found that two arms of the ligand DAPSC can be opened to accept the La(Ⅲ). This is obviously different from the complex of Sm(Ⅲ) with DAPSC. DAPSC can be expanded easily, but it is hard to be compressed.
