6-(2,6-Dimethyl-phen-yl)pyrido[2,3-d]pyrimidin-7-amine.

ABSTRACT: In the title compound, C(15)H(14)N(4), the pyrido[2,3-d]pyrimidine system is almost ideally planar (r.m.s. deviation 0.028?Å) with its mean plane almost orthogonal to the 2,6-dimethyl-phenyl plane. The dihedral angle formed by these planes [87.3?(2)°] is close to the predicted value (89.7°) obtained by mol-ecular-mechanics force-field calculations. Only one of the two active amine H atoms participates in hydrogen bonding, which links mol-ecules into centrosymmetric dimers.

N-(2,6-Dimethyl-phen-yl)benzamide.

Project description:The title compound, C(15)H(15)NO, crystallizes with two mol-ecules in the asymmetric unit. The H-N-C=O units are in a trans conformation, similar to that observed in N-(3,4-dimethyl-phen-yl)benzamide, N-(2,6-dichloro-phen-yl)benz-amide and other benzanilides. The central -NHCO- bridging unit is tilted at angles of 17.1?(3) and 16.4?(3)° to the benzoyl ring in the two mol-ecules. The two rings (benzoyl and aniline) are almost orthogonal with respect to each other, making dihedral angles of 86.3?(1) and 86.0?(1)° in the two mol-ecules. N-H?O hydrogen bonds link mol-ecules into infinite chains running along the c axis.

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

Project description: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⋯π inter-actions, consolidating the crystal packing.

Project description:The conformation of the N-H bond in the structure of the title compound, C(10)H(13)NO, is syn to both the 2- and 3-methyl substituents on the aromatic ring, and is anti to the C=O bond. N-H?O hydrogen bonds link the mol-ecules into supra-molecular chains.
