The crystal structure of the complex La(Ⅲ) with 1,10-phenanthroline, [La(NO 3) 2(Phen) 2(H 2O) 2]·ClO 4·2Phen·H 2O, was determined by single crystal X-ray diffraction analysis. The crystal belongs to triclinic crystal system, space group Pī with a=11.250(4), b=13.364(4), c=16.327(5), α=103.046(6), β=90.327(6), γ=99.567(6)°, V=2355.8(12) 3, Z=2, Dc =1.603g·cm -3 , F(000) =1148, μ =1.042mm -1 , R =0.0569 and wR=0.1588. X-ray structure analysis reveals that the complex consists of [La(Phen) 2(NO 3) 2(H 2O) 2] + cation, ClO - 4 anion,two co-crystallized Phen molecules and one lattice H 2O molecule. In which, the central La 3+ ion is ten-coordinate with distorted bicapped square antiprism geometry and surrounded by six O atoms from four bidentate NO - 3and two H 2O, and four N atoms from two Phen, respectively. 3D network is formed through intermolecular hydrogen bonds.
