The title compound, Cs3[PuO4(OH)2]·3H2O, contains centrosymmetric [PuO4(OH)2]3- anions. The Pu atom in this anion has an almost ideal tetragonal bipyramidal oxygen environment. The Pu-O distances are 1.8889 (14) and 1.8685 (15) Å in the PuO4 group and 2.3726 (15) Å to the OH groups. In the isostructural NpVII compound, Cs3[NpO4(OH)2]·3H2O, the Np-O distances in the NpO4 group are nearly the same as the Pu-O distances here, but the distances to the OH groups are about 0.04 Å longer.

ABSTM02_ALERT_3_G When printed, the submitted absorption T values will be
replaced by the scaled T values. Since the ratio of scaled T's
is identical to the ratio of reported T values, the scaling
does not imply a change to the absorption corrections used in
the study.

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. |
