چکیده
In the title compound, C(11)H(10)N(2)O(2), the benzene ring faces towards one of the pyrimidine N atoms, and is almost orthogonal to the plane through the pyrimidine ring [dihedral angle = 84.40 (14)°]. In the crystal, the presence of C-H⋯π and π-π [centroid-centroid separation = 3.7658 (18) Å] inter-actions leads to a supra-molecular array in the ac plane. The layers thus formed inter-digitate along the b axis.

In the title compound, C(15)H(10)Cl(2)N(4)O(2), the dichloro-pyrimidine and meth-oxy-phen-oxy parts are approximately perpendicular [dihedral angle = 89.9 (9)°]. The dihedral angle between the two pyrimidine rings is 36.3 (4)° In the crystal, there are no hydrogen bonds but the mol-ecules are held together by short inter-molecular C⋯N [3.206 (3) Å] contacts and C-H⋯π inter-actions.

The title compound, C15H12N4O4·2H2O, crystallizes with two independent water mol-ecules in the asymmetric unit. The dihedral angles between the mean planes of the benzene and pyrimidine rings and that of the pyrimidin-4-one ring are 85.1 (9) and 82.1 (1)°, respectively. The mean plane of the pyrimidine ring is twisted by 12.8 (8)° from that of the pyrimidin-4-one ring. The dihedral angles betwe...

The title compound, C(9)H(12)N(2)O(3), was synthesized by the reaction of ethyl 2-(4-meth-oxy-phen-oxy)acetate with hydrazine hydrate in ethanol. In the acetohydrazide group, the N-N bond is relatively short [1.413 (2) Å], suggesting some degree of electronic delocalization in the mol-ecule. In the crystal, mol-ecules are linked into sheets lying parallel to the ab plane by N-H⋯N and N-H⋯O hydr...
