Bis{2,6-bis­[(2-hy­droxy-5-methyl­phen­yl)imino­meth­yl]pyridine} monohydrate

By Muhammet Kose and Vickie McKee


The title compound, 2C21H19N3O2·H2O, was synthesized by a Schiff base condensation of 2,6-diformyl­pyridine with 2-amino-4-methyl­phenol in ethanol. In the crystal, two mol­ecules of 2,6-bis­[(2-hy­droxy-5-methyl­phen­yl)imino­meth­yl]pyridine dimer­ize via hydrogen bonding to a water mol­ecule, which lies on a twofold axis. There are also intra­molecular phenol–imine hydrogen bonds. The dimers are further linked via π–π (phen­yl–pyridine) [centroid–centroid distance = 3.707 (2) Å] and π–π edge-to-edge [3.392 (2) Å] inter­actions. The dihedral angles between the central ring and the two pendant rings are 11.46 (8) and 2.06 (8)° while the pendant rings make a dihedral angle of 10.14 (8)°
