Six uranyl ion complexes with 1,2,3,4-cyclobutanetetracarboxylic acid (H4CBTC) and one with 1,2,3,4-butanetetracarboxylic acid (H4BTC) have been obtained under solvo-hydrothermal conditions in the presence of diverse, organic or metallic counterions. The different conformations found for the cyclic ligand (cis,trans,cis or trans,trans,trans in most cases, with one instance of cis,trans,trans), the
