| Abstract: | Structural characterization of a hydrogen sulfate complex with a tren-based urea suggests that the anion is coordinated with six NH···O bonds (d(N···O) = 2.857 (3) to 3.092 (3) ?) and one OH···O bond (d(O···O) = 2.57 (2) ?) from three receptors; however, in solution the anion is bound within the pseudo-cavity of one receptor. |
