A 3D chiral hydrogen bond framework based on phenanthrolinium hydrogen 4,5-dichlorophthalate: Crystal structure and luminescent properties

摘要

A salt with the composition [C _(12)H _9N _2][C _8H _3Cl _2O _4] (1) with 4,5-dichlorophthalic acid and 1,10-phenanthroline (phen) has been synthesized and characterized by IR, UV spectroscopy, elemental analysis, and X-ray crystallography. Compound 1 represents a 3D chiral supramolecular framework containing monohelical chains (2 _1 axis) through multiform C-H O, ? O-H ? O, N-H ? N intramolecular hydrogen bonds and C-H ? O, N-H ? O intermolecular hydrogen bonds. Otherwise, two types of face-to-face φ ? interactions between the aromatic rings are found in the solid state. The luminescent properties of compound 1 were investigated in the solid state at room temperature.
