Interlocked aromatic species: Crystal structure and Hirshfeld surface analysis of the uranyl ion complex of 3-(pyrimidin-2-yl)benzoate with Ni(phen)(3)(2+) counter-ions

摘要

The reaction of uranyl nitrate with 3-(pyrimidin-2-yl)benzoic acid (LH) in the presence of nickel(II) nitrate and 1,10-phenanthroline (phen) yields the complex [Ni(phen)(3)][UO2(L)(3)](2)center dot 2.5H(2)O (I), in which the uranium atom is chelated by three carboxylate groups. Analysis of short intermolecular contacts shows that those associated with pi center dot center dot center dot pi interactions do not show up prominently, notwithstanding the number of aromatic rings present, and the packing mode appears to be primarily a result of Coulombic interactions and best shape fitting.
