Crystal structure of 1,1'-(pyridine-2,6-di-yl)bis-[N-(pyridin-2-ylmeth-yl)methanaminium] dichloride dihydrate.


ABSTRACT: In the title compound, C19H23N5 2+·2Cl-·2H2O, the two pyridine side arms are not coplanar, with the terminal pyridine rings subtending a dihedral angle of 26.45 (6)°. In the crystal, hydrogen bonds, inter-molecular C-H⋯Cl contacts and a weak C-H⋯O inter-action connect the mol-ecule with neighbouring chloride counter-anions and lattice water mol-ecules. The crystal packing also features by π-π inter-actions with centroid-centroid distances of 3.4864 (12) and 3.5129 (13) Å.
