Abstract

Co-crystallization of two urea-functionalized ligandswith tetrabutylammonium (TBA) dihydrogen phosphate resulted in the isolation of discrete (H₂PO₄^-)₄ and (H ₂PO₄^-)₆ clusters 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.
