Co-crystallization of two urea-functionalized ligands with tetrabutylammonium (TBA) dihydrogen phosphate resulted in the isolation of discrete (H2PO4-)(4) and (H2PO4-)(6) dusters stabilized in the crystalline state by multiple urea hydrogen bonds. Structural analysis by single-crystal X-ray diffraction, combined with a Cambridge;Structural Database survey of (H2PO4-)(n) aggregates, established that these clusters display unique topologies and hydrogen-bonding connectivities.
