N 4,N 6-Dimethyl-5-nitro-N 4,N 6-diphenylpyrimidine-4,6-diamine
In the title compound, C(18)H(17)N(5)O(2), the pyrimidine ring makes dihedral angles of 66.09 (12), 71.39 (13) and 56.7 (3)° with two phenyl rings and the nitro group, respectively. The dihedral angle between the two phenyl rings is 44.05 (14)°.

In the title compound, C(18)H(19)N(5), the pyrimidine ring makes dihedral angles of 56.49 (9) and 70.88 (9)° with the phenyl rings. The dihedral angle between the two phenyl rings is 72.45 (9)°. No significant inter-molecular inter-actions are observed in the crystal structure.
متن کاملN 2,N 2,N 4,N 4,N 6,N 6-Hexapropyl-1,3,5-triazine-2,4,6-triamine
The title compound, C(21)H(42)N(6), was prepared by the reaction of 2,4,6-trichloro-1,3,5-triazine with dipropyl-amine. The structure of the mol-ecule is tripodal.
متن کامل6-Chloro-N 4-methyl-N 4-phenylpyrimidine-4,5-diamine
In the title compound, C(11)H(11)ClN(4), the dihedral angle between the aromatic rings is 66.47 (8)°. In the crystal, mol-ecules are linked by N-H⋯N hydrogen bonds, generating C(5) chains propagating in [010]. Slipped aromatic π-π stacking between centrosymmetrically related pairs of pyrim-idine rings also occurs [centroid-centroid separation = 3.7634 (12)Å and slippage = 1.715 Å].
متن کامل6-Chloro-N 4,N 4-dimethylpyrimidine-2,4-diamine
The asymmetric unit of the title compound, C(6)H(9)ClN(4), contains four independent mol-ecules (A, B, C and D). Their main difference is the torsion angles, ranging from 1.6 (5) to 5.9 (5)°, between the methyl group and the pyrimidine plane. A pair of inter-molecular N-H⋯N hydrogen bonds link mol-ecules A and C into a twisted dimer with a dihedral angle of 32.9 (1)° between the two pyrimidine ...
