Dicyclo-hexyl-ammonium 3-[(hy-droxy-meth-yl)carbamo-yl]propano-ate.

The title compound, C(12)H(24)N(+)·C(5)H(8)NO(4) (-), contains one dicyclo-hexyl-ammonium cation and one 3-[(hy-droxy-meth-yl)carbamo-yl]propano-ate anion in the asymmetric unit. In the crystal, the ions are linked by inter-molecular N-H⋯O and O-H⋯O hydrogen bonds, forming chains propagating along [100].

N,N'-(Phenyl-imino-dimethyl-ene)di-prop-2-enamide hemihydrate.

In the title compound, C(14)H(17)N(3)O(2)·0.5H(2)O, the asymmetric unit consists of an N,N'-(phenyl-imino-dimethyl-ene)diprop-2-enamide mol-ecule and one half-mol-ecule of water, with the O atom of the latter having 2 site symmetry. The supra-molecular architecture is framed by the inter-play of two-dimensional networks of both O-H⋯O and N-H⋯O inter-actions supported by C-H⋯O and edge-to-face C-H⋯π inter-actions.
