4,6-Dichloro-5-methoxypyrimidine
The mol-ecule of the title compound, C(5)H(4)Cl(2)N(2)O, is close to being planar (r.m.s. deviation = 0.013 Å), apart from the C atom of the meth-oxy group, which deviates by 1.082 (2) Å from the mean plane of the other atoms. In the crystal, short Cl⋯N contacts [3.0940 (15) and 3.1006 (17) Å] generate a three-dimensional framework.
متن کامل2,4-Dichloro-N-o-tolylbenzamide
In the title compound, C(14)H(11)Cl(2)NO, the central C-C(O)-N-C amide unit makes dihedral angles of 68.71 (11) and 54.92 (12)°, respectively, with the dichloro-benzene and tolyl rings. The two aromatic rings are inclined at 16.25 (17)°. In the crystal, N-H⋯O hydrogen bonds link mol-ecules into zigzag chains propagating in [001]. C-H⋯Cl contacts link these chains and additional C-H⋯O contacts g...
متن کامل4,4′-Dichloro-N,N′-(o-phenylene)dibenzenesulfonamide
The title compound, C(18)H(14)Cl(2)N(2)O(4)S(2), is a diamine that is a precursor to a quinonoid bidentate redox-active ligand. The dihedral angles between the central phenyl ring and the end rings are 87.5(1) and 60.7(1)°, while the two end rings make a dihedral angle of 82.5(1)°. The crystal structure is stabilized by two weak inter-molecular N-H⋯O hydrogen bonds, as well as one intra-molecul...
متن کاملMethyl 4′,5-dichloro-2-hydroxy-4,6-dimethylbiphenyl-3-carboxylate
In the title compound, C(16)H(14)Cl(2)O(3), the dihedral angle between the mean planes of the two benzene rings is 55.30 (5)°. The methyl ester group lies within the ring plane due to an intra-molecular O-H⋯O hydrogen bond [maximum deviation from the C(8)O(2) mean plane is 0.0383 (13) Å]. In the crystal, mol-ecules are held together by rather weak C-H⋯O hydrogen bonds.
متن کامل4,6-Dichloro-5-(2-methoxyphenoxy)-2,2′-bipyrimidine
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.
