6-(4-Amino-phen-yl)-4-(4-eth-oxy-phen-yl)-2-meth-oxy-nicotinonitrile.

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?? inter-actions are also present.

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 bon  ...[more]
