Crystal structure of (E)-2-(4-methoxystyryl)-2,3-dihydro-1H-perimidine acetonitrile monosolvate
The title compound, C20H18N2O·CH3CN, a perimidine deriv-ative, crystallized as an aceto-nitrile monosolvate. The planes of the naphthalene ring system and the meth-oxy-phenyl ring are oriented almost perpendicular to one another, with a dihedral angle of 87.61 (6)°. The conformation about the C=C bond is E. The hexa-hydro-pyrimidine ring has an envelope conformation, with the methine C atom as ...

The title compound, C(13)H(14)N(2), was obtained from reaction of diaminona-phthalene with acetone. In both independent mol-ecules in the asymmetric unit, the tricyclic perimidine consists of a planar (r.m.s. deviations = 0.0125 and 0.0181 Å) naphthalene ring system and an envelope conformation C(4)N(2) ringwith the NCN group hinged with respect to the naph-thalene backbone by 36.9 (2) and 41.3...
متن کامل2-Ethoxy-6-[1-(3-ethoxy-2-hydroxybenzyl)-2,3-dihydro-1H-benzimidazol-2-yl]phenol acetonitrile monosolvate
The title compound, C(24)H(24)N(2)O(4)·CH(3)CN, a disubstituted benzimidazole, crystallized as an acetonitrile monosolvate. The benzene ring of the 2-eth-oxy-6-methyl-phenol substiuent is approximately perpendicular to the nearly planar benzimidazole ring system [maximum deviation = 0.016 (1) Å], making a dihedral angle of 84.27 (8)°. The benzene ring of the 2-eth-oxy-phenol substituent is incl...
متن کامل4-[(1,3-Dioxo-2,3-dihydro-1H-benzo[de]isoquinolin-2-yl)methyl]-N′-[(E)-4-nitrobenzylidene]benzenesulfonohydrazide dimethyl sulfoxide monosolvate
The mol-ecular structure of the title compound, C(26)H(18)N(4)O(6)S·C(2)H(6)OS, shows an E conformation of the hydrazone double bond. The presence of a methyl-ene group between the benzo[de]isoquinoline and benzene-sulfonyl moieties allows the 4-nitro-phenyl ring and the benzo[de]isoquinoline system to be parallel with respect to each other, so that the mol-ecule adopts a U-shaped spatial confo...
متن کاملCrystal structure of 1-methyl-2-[(E)-2-(4-methylphenyl)ethenyl]-4-nitro-1H-imidazole
In the title mol-ecule, C13H13N3O2, the planes of the benzene and imidazole rings form a dihedral angle of 7.72 (5)°. In the crystal, mol-ecules are linked by weak C-H⋯N and C-H⋯O hydrogen bonds, forming layers parallel to (100). A weak C-H⋯π inter-action connects these layers into a three-dimensional network. A π-π stacking inter-action, with a centroid-centroid distance of 3.5373 (9) Å, is al...
