dc.description.abstractIn the asymmetric unit of the title nicotinonitrile derivative, C 23H21BrN2O4, 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) ]. Weak intra-molecular C- H?N inter-actions generate S(5) ring motifs. In the crystal structure, the mol-ecules are linked by weak inter-molecular C- H?N and C- H?O inter-actions into a supra-molecular three-dimensional network in such a way that the nicotinonitrile units of neighboring mol-ecules are stacked in an anti-parallel manner along the c axis. The crystal is further stabilized by C- H?? inter-actions.en_US
