Crystal structure of (pyridin-2-ylmethylidene)(triphenylmethyl)amine

Abstract

The title Schiff base compound, C25H20N2, crystallizes with two independent mol­ecules (A and B) in the asymmetric unit. In both mol­ecules, the imine group is approximately coplanar with the pyridine ring, with N—C—C—N torsion angles of 170.1 (3) and −172.0 (3) Å. In the crystal, A and B dimers are linked by pairs of C—H⋯π inter­actions and further C—H⋯π bonds link the dimers into a three-dimensional network.

“…All reagents were of analytical grade and were used as received without further purification. The bidentate Schiff base ligand, 2,4,6-trimethyl-N-[(pyridin-2-yl)methylidene]aniline (C 15 H 16 N 2 or PM-TMA) was synthesized according to a literature method (Theppitak et al, 2014). A solution of PM-TMA (89.7 mg, 0.4 mmol) in methanol (5 ml) was placed in a test tube.…”
