1,1′-Methylenedipyridinium dichloride monohydrate
نویسندگان
چکیده
In the crystal structure of the title salt, C(11)H(12)N(2) (2+)·2Cl(-)·H(2)O, the dication adopts a butterfly shape [dihedral angle between rings = 69.0 (1)°] with the water mol-ecule lying in the V-shaped cavity. Each O-H bond of the water molecule lies parallel to an aromatic ring and forms an O-H⋯Cl inter-action to a chloride anion. The methyl-ene C atom in the dication and the water O atoms lie on special positions of twofold site symmetry.

In the title compound, C(18)H(24)N(2) (2+)·2Cl(-)·H(2)O, both the cation and the water mol-ecule lie on a twofold crystallographic axis. In the cation, the two benzene rings are perpendicular to each other, making a symmetry-constrained dihedral angle of 90°. In the crystal, N-H⋯Cl, O-H⋯Cl and N-H⋯O hydrogen bonds result in the formation of a three-dimensional network.
