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

Nukui S, Rheingold AL, Dipasquale A, Yanovsky A - Acta Crystallogr Sect E Struct Rep Online (2009)

Bottom Line: 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.

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.
