N-(3-Methyl-phen-yl)pyrimidin-2-amine.

ABSTRACT: Two independent mol-ecules comprise the asymmetric unit in the title compound, C(11)H(11)N(3). These differ in terms of the relative orientations of the aromatic rings: the first is somewhat twisted, while the second is approximately planar [dihedral angles between the pyrimidine and phenyl rings = 39.00?(8) and 4.59?(11)°]. The mol-ecules also form distinct patterns in their hydrogen bonding. The first independent mol-ecule forms centrosymmetric dimers featuring an eight-membered {HNCN}(2) synthon. The second independent mol-ecule forms an N-H?N hydrogen bond with the other pyrimidine N atom of the first mol-ecule. Thereby, tetra-meric aggregates are formed. These associate via C-H?N and C-H?? inter-actions, consolidating the crystal packing.

Project description:In the title compound, C(11)H(10)ClN(3)S, the dihedral angle between the benzene and pyrimidine rings is 3.99?(4)°. In the crystal, inter-molecular N-H?N hydrogen bonds link the mol-ecules into ribbons of R(2) (2)(8) rings parallel to [100]. Weak C-H?S contacts connect adjacent ribbons into a two-dimensional undulating layer-like structure extending parallel to (110). The benzene and pyrimidine rings of adjacent mol-ecules have the offset face-to-face ?-? stacking inter-actions in a zigzag fashion along the c axis, with perpendicular ring distances of 3.463 and 3.639?Å, and a dihedral angle between the planes of 3.99?(2)°. The distance between the ring centroids is 4.420?(2)?Å.

N-(5-Amino-2-methyl-phen-yl)-4-(3-pyri-dyl)-pyrimidin-2-amine.

Project description:The title compound, C(16)H(15)N(5), crystallizes with two independent mol-ecules (A and B) in the asymmetric unit.

5-[(4-Eth-oxy-anilino)meth-yl]-N-(2-fluoro-phen-yl)-6-methyl-2-phenyl-pyrimidin-4-amine.

Project description:The asymmetric unit of the title compound, C(26)H(25)FN(4)O, consists of two symmetry-independent mol-ecules, denoted A and B. The conformation of each mol-ecule is mainly determined by an intra-molecular N-H?N hydrogen bond, which closes a six-membered ring. The dihedral angles between the pyrimidine ring and the phenyl, fluorophenyl and ethoxyphenyl rings are 15.4?(2), 28.4?(2) and 77.5?(2)°, respectively, in mol-ecule A, and 15.9?(2), 2.7?(2) and 61.8?(2)° in mol-ecule B. Inter-molecular N-H?N hydrogen bonds and ?-? stacking inter-actions between pyrimidine rings [centroid-centroid distance = 3.692?(4)?Å] connect mol-ecules A and B into dimers and C-H?O hydrogen bonds link the dimers into zigzag chains along [011]. The (4-eth-oxy-anilino)methyl group of the B mol-ecule is disordered over two sets of sites, the occupancy factor for the major component being 0.900?(2).

N-(4-Meth-oxy-phen-yl)-6-methyl-2-phenyl-5-{[4-(tri-fluoro-meth-yl)anilino]meth-yl}pyrimidin-4-amine.

Project description:The title compound, C26H23F3N4O, crystallizes with two symmetry-independent mol-ecules in the asymmetric unit, denoted A and B, which differ mainly in the rotation of the meth-oxy-phenyl ring. The -CF3 group of mol-ecule B is disordered by rotation, with the F atoms split over two sets of sites; the occupancy factor for the major component is 0.853?(4). The dihedral angles between the pyrimidine ring and the attached phenyl, meth-oxy-phenyl and tri-fluoro-methyl-phenyl rings are 8.1?(2), 37.5?(2) and 70.7?(2)°, respectively, in mol-ecule A, and 9.3?(2), 5.3?(2) and 79.7?(2)° in mol-ecule B. An intra-molecular N-H?N hydrogen bond occurs in each mol-ecule. In the crystal, two crystallographically independent mol-ecules associate into a dimer via a pair of N-H?N hydrogen bonds, with a resulting R 2 (2)(12) ring motif and ?-? stacking inter-actions [centroid-centroid distance = 3.517?(4)?Å] between the pyrimidine rings. For the A mol-ecules, there are inter-molecular C-H?O hydrogen bonds between an aryl C atom of meth-oxy-phenyl ring and a meth-oxy O atom of an adjacent mol-ecule. A similar inter-action is lacking in the B mol-ecules.
