Crystal structure of (E)-2-amino-4-methylsulfanyl-6-oxo-1-{[(thiophen-2-yl)methylidene]amino}-1,6-dihydropyrimidine-5-carbonitrile
The title compound, C11H9N5OS2, a 1-thio-phen-2-yl-methyl-ene-amino-pyrimidine derivative, displays an essentially planar C-NH2 group. The conformation across the N=C bond linking the pyrimidine and thienyl groups is E. The pyrimidine and thienyl ring systems subtend an inter-planar angle of 42.72 (5)°. In the crystal, mol-ecules are linked by N-H⋯Nnitrile and N-H⋯O=C hydrogen bonds, forming ch...

In the title compound, C(15)H(11)N(3)O(4)S, the dihedral angle between the mean planes of the dihydro-indol-2-one (r.m.s. deviation = 0.015 Å) and dihydro-thieno[3,2-b]pyran (r.m.s. deviation = 0.011 Å) ring systems is 89.53 (3)°. The crytal packing is consolidated by inter-molecular N-H⋯O and N-H⋯N hydrogen bonds, which link the mol-ecules into a two-dimensional network into sheets lying paral...
متن کامل2-Amino-7-oxo-4,5,6,7-tetrahydro-1-benzothiophene-3-carbonitrile
In the title compound, C(9)H(8)N(2)OS, the benzothio-phene ring is substituted with amino, oxo and carbonitrile groups. The thio-phene ring is essentially planar (r.m.s. deviation = 0.0003 Å), while the cyclo-hexene ring is in a half-chair conformation. In the crystal, N-H⋯O hydrogen bonds generate chains of mol-ecules in a zigzag pattern along the b axis. Pairs of N-H⋯N hydrogen bonds form cen...
متن کاملTheoretical characterization of 5 - oxo , 7 - oxo and 5 - oxo - 7 - amino [ 1 , 2 , 4 ] triazolo [ 1 , 5 - a ] pyrimidines †
Accurate ab initio calculations at the B3LYP/6-311 G** level have been performed on anionic and neutral structures of 4,5-dihydro-5-oxo[1,2,4]triazolo[1,5-a]pyrimidine, 4,7-dihydro-7-oxo[1,2,4]triazolo[1,5-a]pyrimidine, and 4,5-dihydro-7-amino-5-oxo[1,2,4]triazolo[1,5-a]pyrimidine compounds. The quality of the theoretical results has been tested against the experimental X-ray structures for the...
