6-(4-Bromo-phen-yl)-2-eth-oxy-4-(2,4,6-trimethoxy-phen-yl)nicotinonitrile.

ABSTRACT: In the asymmetric unit of the title nicotinonitrile derivative, C(23)H(21)BrN(2)O(4), there are two non-planar independent mol-ecules. The central pyridine ring makes dihedral angles of 9.05 (7) and 77.06 (7)°, respectively, with the 4-bromo-phenyl and 2,4,6-trimethoxy-phenyl rings in one mol-ecule, whereas the corresponding values are 5.96 (7) and 82.37 (7)° in the other. All the three meth-oxy groups are essentially in the plane of the attached benzene ring [C-O-C-C angles = 2.99 (19), 4.8 (2) and -6.2 (2)° in one mol-ecule, and 2.69 (18), 176.73 (15) and 1.3 (2)° in the other]. The eth-oxy group is slightly twisted in one mol-ecule [C-C-O-C = 173.84 (12)°], whereas it is coplanar with the pyridine ring in the other [C-C-O-C = -177.23 (13)°].
