A novel supramolecular complex [Cu (Hhbd) (phen) 2] was synthesized by the reaction of the chelate ligand 1,10-phenanthroline (phen) with hydroxy succinate .2CH3OH, the crystal structure was determined by single crystal diffraction and characterized by elemental analysis, infrared spectroscopy and thermal analysis. The complex belongs to the triclinic system with space group P-1. The unit cell parameters are a = 1.20624 (17) nm, b = 1.6598 (2) nm, c = 1.6863 (3) nm, β = 71.262 (3), ° γ = 117.23 (9); ° Z = 4; final deviation factor R = 0.0420. Each Cu (Ⅱ) atom in the complex coordinates with one O atom from four N atoms and two hydroxides (Hhbd) from two phen to form a distorted triangular bipyramidal structure unit. The adjacent mononuclear units form a one-dimensional zigzag supramolecular chain through the π-π stacking effect between the phen molecules and the synergistic interaction of the carboxyl O and the hydroxyl O of Hhbd with the CH ... O hydrogen bonds between the C atoms of the phen ring. The adjacent super The molecular chain links two different hydrogen bond interactions to build a two-dimensional supramolecular system.
