摘要
The crystal structure of Ce(NO3)5(H3O)2 · H2O has been determined from three-dimensional single crystal X-ray diffraction data. Crystals are monoclinic, space group P2/c, with a = 21.364(7), b = 7.8990(7), c = 15.133(2) Å β = 91.02(2)°, and Z = 8. Full matrix anisotropic least-squares techniques led to a conventional R factor of 0.049 for 4067 observed reflections. The structure consists of infinite and isolated chains running parallel to [100]. The cerium atoms are twelvefold coordinated by six bidentate nitrate groups. The chains are held together by hydrogen bonds through hydronium ions and water molecules located between the chains. © 1993 Academic Press, Inc.
