Abstract

The structure of KTh2(P04h has been determined .from threedimensional
X-ray data. The crystals are monoclinic with a= 17.57,
b = 6.863, c = 8.138 A, B = 101° 46', Dx = 5.45 g · cm-3• The space
group is C2/c and there are four formula urnts per unit cell. It
follows from the interatomic distances that the compound is potassium
tr.isphosphatodithorate defined by . the formula K [Th2(P04)a].
Nine oxygen atoms are bound to the thorium atom; their distances
range from 2.26 to 2.66 A. Eight oxygen atoms are coordinated
around potass·ium atom; their distances range from 2.74 to 3.09 A . .
The distances in the P04 groups do not deviate significantly from
known data.
