Bis{2,6-bis-[(2-hy-droxy-5-methyl-phen-yl)imino-meth-yl]pyridine} monohydrate.

ABSTRACT: The title compound, 2C(21)H(19)N(3)O(2)·H(2)O, was synthesized by a Schiff base condensation of 2,6-diformyl-pyridine with 2-amino-4-methyl-phenol in ethanol. In the crystal, two mol-ecules of 2,6-bis-[(2-hy-droxy-5-methyl-phen-yl)imino-meth-yl]pyridine dimer-ize via hydrogen bonding to a water mol-ecule, which lies on a twofold axis. There are also intra-molecular phenol-imine hydrogen bonds. The dimers are further linked via ?-? (phen-yl-pyridine) [centroid-centroid distance = 3.707?(2)?Å] and ?-? edge-to-edge [3.392?(2)?Å] inter-actions. 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)°.
