Structural characterization of a hydrogen sulfate complex with a tren-based urea suggests that the anion is coordinated with sixNH Obonds (dN O = 2.857 (3) to 3.092 (3)A ) and one OH O bond (dO O = 2.57 (2) A ) from three receptors; however, in solution the anion is bound within the pseudocavity of one receptor.
