Abstract : Depending on the counterion, uranyl tricarballylate, UO2(tca)−, is shown to crystallize either as two-dimensional nets or as one-dimensional tubules, all with honeycomb topology and united into higher dimensional assemblies when additional metal cations (AgI, PbII) are present. A regular geometric progression involving ligand reorientation is apparent in the series, with triangular furrows in [H2NMe2][UO2(tca)]·H2O (1) followed by deepening square grooves in [UO2Ag(tca)(H2O)]·0.5H2O (2) and full closure of square tubules in [NH4][(UO2)2Pb(tca)2(NO3)(bipy)].
