The structure of a novel mixed-valent chromium uranyl compound, (C 3NH 10) 10[(UO 2) 13(Cr 12 5+O 42)(Cr 6+O 4) 6(H 2O) 6](H 2O) 6 (1), obtained by the combination of a hydrothermal method and evaporation from aqueous solutions with isopropylammonium, contains uranyl chromate hemispheres with lateral dimensions of 18.9 × 18.5 Å 2 and a height of about 8 Å. The hemispheres are centered by a UO 8 hexagonal bipyramid surrounded by six dimers of Cr 5+O 5 square pyramids, UO 7 pentagonal bipyramids, and Cr 6+O 4 tetrahedra. The hemispheres are linked into two-dimensional layers so that two adjacent hemispheres are oriented in opposite directions relative to the plane of the layer. From a topological point of view, the hemispheres have the formula U 21Cr 23 and can be considered as derivatives of nanospherical cluster U 26Cr 36 composed of three-, four-, and five-membered rings.
