(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...
متن کامل6-Amino-1,3-dimethyl-5-[(E)-2-(methylsulfanyl)benzylideneamino]pyrimidine-2,4(1H,3H)-dione
The title compound, C(14)H(16)N(4)O(2)S, is a Schiff base derivative of 2-(methyl-sulfan-yl)benzaldehyde. The configuration about the C=N double bond is E. The heterocyclic ring is essentially planar (τ = 3.1°) and makes a dihedral angle of 12.24 (7)° with the benzene ring. An intra-molecular N-H⋯S hydrogen bond is observed. In the crystal, N-H⋯O and C-H⋯O hydrogen bonds link mol-ecules into la...
متن کاملA second monoclinic polymorph of 6-amino-1,3-dimethyl-5-[(E)-2-(methylsulfanyl)benzylideneamino]pyrimidine-2,4(1H,3H)-dione
A new monoclinic form of the title compound, C(14)H(16)N(4)O(2)S, has been identified unexpectedly during an attempt to synthesize a coordination compound. The heterocyclic ring is essentially planar (r.m.s. deviation = 0.005 Å) and makes a dihedral angle of 8.77 (5)° with the benzene ring. This is in contrast to 12.24 (7)° reported for the first monoclinic polymorph [Booysen et al. (2011 ▶). A...
متن کامل2,2-Dimethyl-5-[(pyridin-2-ylamino)methylidene]-1,3-dioxane-4,6-dione
In the title compound, C(12)H(12)N(2)O(4), the dihedral angle between the pyridine and enamine planes is 3.5 (3)°, while the angle between the dioxanedione (seven atoms) and enamine planes is 4.6 (3)°. The dioxane ring approximates an envelope conformation.
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...
