Crystal structure of 4-(4-chlorophenyl)-6-(morpholin-4-yl)pyridazin-3(2H)-one

2015

In the crystal, pairs of centrosymmetrically related mol­ecules are linked into dimers via N—H⋯O hydrogen bonds, forming (8) ring motifs. The dimers are connected via C—H⋯O and C—H⋯Cl hydrogen bonds, forming a three-dimensional network·Semi-empirical mol­ecular orbital calculations were carried out using the AM1 method.

Crystal structure of 2-hy­droxy­imino-2-(pyridin-2-yl)-N'-[1-(pyridin-2-yl)ethyl­idene]acetohydrazide

2014

The mol­ecule of the title compound is approximately planar with the planes of the two pyridine rings inclined to one another by 5.51 (7)°. In the crystal, mol­ecules are linked by bifurcated O—H⋯(O,N) hydrogen bonds, forming inversion dimers, which are in turn linked via C—H⋯O and C—H⋯N hydrogen bonds, forming sheets lying parallel to (502).
