摘要

The compound Rb_2[(UO_2)_2(CrO_4)_3(H_2O)_2] ? 4H_2O was studied by X-ray diffraction. The crystals are monoclinic, a = 10.695(2) ?, b = 14.684(3) ?, c = 14.125(3) ?, β = 108.396(4)°, sp. gr. P2_1/c, Z = 4, V =2104.9(7) ?~3, and R = 0.0491. The main structural units are layers consisting of [(UO_2)_2(CrO_4)_3(H_2O)_2]~(2–) anions belonging to the crystal-chemical group A_2T_2~3B~2M_2~1 (A = UO_2~(2+), T~3 and B~2 are CrO_4~(2-), and M~1 is H_2O) of uranyl complexes. The uranium-containing layered groups are held together by electrostatic interactions with rubidium cations, as well as by hydrogen bonds with the participation of inner- and outer-sphere water molecules.
