The title complexes (LnL_3(HL)(H_2O)]_2·2EtOH·2H_2O (Ln= Nd (1), La (2), HL=adamantanecarboxylic acid) were prepared and determined by single-crystal X-ray diffraction. Both complexes crystallize in triclinic system with space group P 1[TX-], cell parameters are: complex (1) a=1.0556(2) nm, b=1.4913(3) nm, c=1.4920(3) nm, α=106.26(3)°, β=93.51(3)°, γ=97.23(3)°, V=2.2253(5) nm~3, D_ cal=1.409 g·cm~ -3, Z=1, F(000)=990, μ(Mo Kα)=1.225 mm~ -1, M_r=1884.50; complex (2) a=1.0453(2) nm, b=1.4971(3) nm, c=1.5052(3) nm, α=106.07(3)°, β=93.58(3)°, γ=97.56(3)°, V=2.2391(5) nm~3, D_ cal=1.397 g·cm~ -3, Z=1, F(000)=984, μ(Mo Kα)=1.015 mm~ -1, M_r=1877.88. The final R and wR are 0.0396 and 0.1062 for 8589 (I≥2σ(I)) observed reflections for complex (1), 0.0505 and 0.1344 for 8417 (I≥2σ(I)) observed reflections for complex (2), respectively. The crystals are consisted of a binuclear molecule. The coordination geometry of the Ln(Ⅲ) ion can be described as tricapped trigonal prism.
