The crystal structure has been determined by single crystal X-ray diffractometry. The crystal is monoclinic with space group C2/c. The unit cell parameters are as follows: a=16.289(8), b=18.323(8), c=22.044(8) A, β=106.34(2)°, V=6314(6) A3, Z=4 and Dc=1.764 g/cm3. The structure was solved by direct method. The least-square refinement based on 3776 observed reflections [F > 6σ(F)] converged to a final R=8.6% and F(000) is 3548. Yttrium ion with eight-coordinate is located in central of the molecule, the two lanthanum ions with ten-coordinate are located at the two sides of yttrium ion. There are two positions for Na in the molecule, one is in the C2 axis with six coordinate, the other one is in a general position with five-coordinate.展开更多
