Abstract

Two new coordination polymers: Ba2[(UO2)3(suc)3F4]⋅5H2O (I) and Ba[(UO2)2(glt)2(Hglt)F]⋅8H2O (II), where suc is C4H4O2−442− (succinate ion) and glt is C5H6O2−442− (glutarate ion), were synthesized, and their structure was studied. The uranium-containing structural units of crystals I are the [(UO2)3(C4H4O4)3F4]4– layers belonging to the crystal-chemical group A3(Q02)3M22M22M12M21 of uranyl complexes, where A = UO2+2UO22+, Q02 = C4H4O2−442−, М1 and М2 = F–. Structure II contains the uranium-containing 3D complex [(UO2)2(C5H6O4)2(C5H7O4)F]2–, which corresponds to the crystal-chemical formula A2(Q02)2B01M2, where A = UO2+2UO22+, Q02 = C5H6O2−442−, B01 = C5H7O−44−, and М2 = F–.
