Hydrogen bonding in nitroaniline analogues: hydrogen-bonded sheets in 2-amino-4,6-dimethoxy-5-nitropyrimidine and pi-stacked hydrogen-bonded sheets in 4-amino-2,6-dimethoxy-5-nitropyrimidine.
In 2-amino-4,6-dimethoxy-5-nitropyrimidine, C(6)H(8)N(4)O(4), the molecules are linked by one N-H...N and one N-H...O hydrogen bond to form sheets built from alternating R(2)(2)(8) and R(6)(6)(32) rings. In isomeric 4-amino-2,6-dimethoxy-5-nitropyrimidine, C(6)H(8)N(4)O(4), which crystallizes with Z' = 2 in P-1, the two independent molecules are linked into a dimer by two independent N-H...N hy...
متن کاملHydrogen bonding in nitroaniline analogues: a hydrogen-bonded chain of rings in 2-amino-4-butylamino-6-methoxy-5-nitropyrimidine.
In the title compound, C(9)H(15)N(5)O(3), in which the molecules exhibit orientational disorder, the molecules of the major component are linked by paired N-H...O hydrogen bonds [H...O = 2.37 and 2.39 A, N...O = 2.974 (3) and 3.011 (3) A, and N-H...O = 126 and 128 degrees ] to form a C(8)C(8)[R(2)(2)(6)] chain of rings along [010]. The minor component (6.5% of the molecules) forms a similar cha...
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-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.

The title compound, C(19)H(10)BrCl(2)F(3)N(4)O, is an imine with an overall Y shape. The dihedral angles between the pyrazole ring and the methoxy- and trifluoromethyl-substituted benzene ring planes are 88.4 (2) and 65.8 (2)°, respectively.
