Abstract

In the title mol-ecule, C(21)H(19)N(3)O(2), the central pyridine ring makes dihedral angles of 14.46 (9) and 34.67 (8)° with the 4-amino- and 4-eth-oxy-substituted benzene rings, respectively. The eth-oxy group is essentially coplanar with the attached benzene ring [C-O-C-C torsion angle = 178.70 (16)°] as is the meth-oxy group with the pyridine ring [C-O-C-N torsion angle = -3.0 (3)°]. In the crystal, mol-ecules are linked by N-H⋯N hydrogen bonds into chains along [201]. Weak C-H⋯O hydrogen bonds and C-H⋯π inter-actions are also present.

摘要

在标题分子C(21)H(19)N(3)O(2)中，中心吡啶环与4-氨基取代的苯环和4-乙氧基取代的苯环的二面角分别为14.46 (9)°和34.67 (8)°。乙氧基与相连的苯环基本共面[C-O-C-C扭转角 = 178.70 (16)°]，甲氧基与吡啶环也基本共面[C-O-C-N扭转角 = -3.0 (3)°]。在晶体中，分子通过N-H⋯N氢键沿[201]方向连接成链。还存在弱的C-H⋯O氢键和C-H⋯π相互作用。
