(E)-6-Amino-1,3-dimethyl-5-[(pyridin-2-ylmethylidene)amino]pyrimidine-2,4(1H,3H)-dione
In the title compound, C(12)H(13)N(5)O(2), a Schiff-base-derived chelate ligand, the non-aromatic heterocycle and its substituents essentially occupy one common plane (r.m.s. of fitted non-H atoms = 0.0503 Å). The N=C bond is E-configured. Intra-cyclic angles in the pyridine moiety cover the range 117.6 (2)-124.1 (2)°. Intra- and inter-molecular N-H⋯N and N-H⋯O hydrogen bonds are observed in th...

The nitro group in the title compound, C(10)H(9)NO(6), is rotated by 10.9 (5)° out of the plane of the benzene ring.
متن کامل4-Amino-3,5-dimethyl-4H-1,2,4-triazole
In the title compound, C(4)H(8)N(4), inter-molecular N-H⋯N hydrogen bonds involving the amino groups and triazole N atoms form a two-dimensional sheet.
متن کامل2-[(E)-(6-Amino-1,3-dimethyl-2,4-dioxo-1,2,3,4-tetrahydropyrimidin-5-yl)iminomethyl]pyridinium chloride monohydrate
The title compound, C(12)H(14)N(5)O(2) (+)·Cl(-)·H(2)O, is the monohydrate of the hydro-chloride of an oxopurine-derived Schiff base in which protonation took place at the pyridine N atom. The organic cation is essentially planar (r.m.s. of all fitted non-H atoms = 0.0373 Å). In the crystal, N-H⋯O and N-H⋯Cl hydrogen bonds as well as C-H⋯O and C-H⋯Cl contacts connect the different entities into...
متن کامل2,2-Dimethyl-5-{[(4-nitrophenyl)amino]methylidene}-1,3-dioxane-4,6-dione
In the title compound, C(13)H(12)N(2)O(6), the dihedral angle between the benzene ring and the amino-methyl-ene unit is 5.42 (16)°, while the angle between the amino-methyl-ene unit and the dioxane ring is 3.06 (43)°. The dioxane ring shows a half-boat conformation, in which the C atom between the dioxane ring O atoms is 0.464 (10) Å out of the plane. An intra-molecular N-H⋯O hydrogen bond stab...
