title: 2,5-Bis[(3-hy-droxy-prop-yl)amino]-1,4-benzoquinone monohydrate.
abstract: The title compound, C(12)H(18)N(2)O(4)·H(2)O, was obtained as a product of the reaction of hydro-quinone with n-propanol amine. The compound crystallizes as a monohydrate, integrating water into its hydrogen-bonded network. Each diamino-quinone moiety forms two centrosymmetric 10-membered rings through C=O⋯H-N bonds. The resulting bands along [102] are inter-linked through hy-droxy groups and water mol-ecules into three-dimensional network. The chemically equivalent bond lengths in the diamino-quinone moiety exhibit a perceptible discrepancy [e.g. C=O bond lengths differ by 0.016 (2) Å], apparently as a result of asymmetric hydrogen bonding: one O atom serves as an acceptor of one hydrogen bond, whereas the other is an acceptor of two.
