An organically templated neptunium(IV) fluoride compound, {(C2H10N2)[Np2F10]}n, has been synthesized under mild hydrothermal conditions. The compound crystallizes in the monoclinic space group C2/c (No. 15). The structure consists of NpF9 tricapped trigonal prisms connected through edge- and corner-sharing to form infinite two-dimensional [Np2F10]2- sheets, that are separated by the ethylenediammonium dications. The C2H10N22+ cations form hydrogen-bonding interactions with the [Np2F10]2- layers.

Special details top
Geometry. All e.s.d.'s (except the e.s.d. in the dihedral angle between two l.s. planes)
are estimated using the full covariance matrix. The cell e.s.d.'s are taken
into account individually in the estimation of e.s.d.'s in distances, angles
and torsion angles; correlations between e.s.d.'s in cell parameters are only
used when they are defined by crystal symmetry. An approximate (isotropic)
treatment of cell e.s.d.'s is used for estimating e.s.d.'s involving l.s.
planes. |
Refinement. Refinement of F2 against ALL reflections. The weighted R-factor
wR and goodness of fit S are based on F2, conventional
R-factors R are based on F, with F set to zero for
negative F2. The threshold expression of F2 >
σ(F2) is used only for calculating R-factors(gt) etc.
and is not relevant to the choice of reflections for refinement.
R-factors based on F2 are statistically about twice as large
as those based on F, and R- factors based on ALL data will be
even larger. |
