The Crystal Structure of the Complex [Y(H20)s(N03)2] [Y(H20)2(N03)4]

The title compound was prepared by thermal d\u27ecomposition of crystals of Y (H20)4(N03)s · 2H20. The structure was solved by. Patterson and Fourier methods and isotropically refined to R=0.12. The unit cell is orthorhombic; the space group is C2221 The crystal contains two crystallographically and chemically different complex ions, with yttrium atoms as the center of the complexes. The coordination number of the ion Y (H20h(N08)4 is 10, while the ion Y (H20)5(N03)2 has coordination number 9
