2,5-Bis[(3-hydroxypropyl)amino]-1,4-benzoquinone monohydrate

2,5-Bis[(3-hy­droxy­prop­yl)amino]-1,4-benzoquinone monohydrate

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 w...

12β,14-Dihy­droxy-3-oxo-5β,20(22)-cardenolide monohydrate

The title compound, digoxigenone, C(23)H(30)O(5)·H(2)O, was biotransformed from digoxigenin. In the crystal, inter-molecular O-H⋯O hydrogen bonds contribute to the formation of a three-dimensional supra-molecular structure. The title compound has three fused six-membered rings (A,B,C) and two non-fused five-membered rings (D,E). As in other structures, compound nucleus has a cis-trans-cis confo...

o-Benzoquinone dioxime

The title compound, C(6)H(6)N(2)O(2), was obtained as a product of an in vitro study of the metabolism of benzofuroxan. The molecule exhibits a amphi configuration of the oxime groups C=N-OH. One oxime group is involved in the formation of a strong intra-molecular O-H⋯N hydrogen bond, while another links mol-ecules into zigzag chains along the c axis via inter-molecular O-H⋯N hydrogen bonds.

The title compound, C(24)H(14)O(9)·H(2)O, displays a cup-shaped form. The water mol-ecule is disordered over two set of sites with an occupancy ratio of 0.78:0.22. The mol-ecule of the compound has four stereocenters and corresponds to the SSRR/RRSS diastereoisomer. In the mol-ecule, the maximum dihedral angle between the planar benzene rings is 80.40 (4)°. The H atoms of the hy-droxy groups ar...
