6-Methoxy-4-(2,4,5-trimethoxyphenyl)-2,2′-bipyridine-5-carbonitrile

Abstract

In the title 3-cyano­pyridine derivative, C21H19N3O4, the 3-cyano-substituted pyridine ring forms dihedral angles of 2.35 (5) and 41.60 (5)° with the unsubstituted pyridine and 2,4,5-trimeth­oxy-substituted benzene rings, respectively. The dihedral angle between the unsubstituted pyridine and benzene rings is 39.84 (5)°. The meth­oxy groups form Cmeth­yl—O—C—(C,N) torsion angles in the range 0.80 (15)–11.45 (15)°. In the crystal, mol­ecules related by 21 screw axes are linked by weak C—H⋯N hydrogen bonds along [010]. In addition, weak C—H⋯π inter­actions and π–π stacking inter­actions between pyridine rings, with a centroid–centroid distance of 3.6448 (6) Å, are observed.

“…The cyano group is also roughly co-planar with the pyridine ring with an rms deviation of 0.0406 (1) Å from the ring plane. The bond distances in (I) agree with the literature values (Allen et al, 1987) and are comparable to those found in closely related structures (Chantrapromma et al, 2013 andSuwunwong et al, 2012;).…”
