Sažetak
Crystals of the title compound, yielded from two preparations
performed in the same way, crystallize in two different space
groups, C2/c and P21/c, retaining the same unit cell. Their structure
has been determined by the heavy-atom method, using three
sets of X-ray intensity datao, the film data in C2/c and the film
and diffractometer data in P2i/c space groups; corresponding R
values were 0.107, 0.092, and 0.044, respectively. Results obtained
from these three independent determinations have shown for the
most part, insignificant differences. The structure is discussed on
the basis of more accuraote diffractometer data.
There aore eight formula units in the unit cell with dimensions
(diffractometer data): a= 0.7055(4), b = 2.166(1), c = 0.9095(5) nm,
p = 111.56(2)0 , V = 1.293(1) nm3•
Of two crystallographically different Th atoms, one is surrounded
by 10 and the other by 8 neighbouring 0 atoms. Their
polyhedra form a weakly connected dimer sharing a common edge,
defined by the two O atoms having the longest Th-0 distances in
the both Th polyhedra, but being nearer to one of the Th atoms.
Crystallographically different Na atoms (four in P21/c and
two in C2/c space groups) are surrounded by 8 to 10 0 atoms.
Metal polyhedrao are mutually connected by common corners, edges,
and planes. Eaoch O atom is common at least to two and at most to
four metal polyhedra.
