【摘要】 A cocrystal based on 1,3-di(4-pyridyl)propane and 3-((4′-carboxybenzyl)oxy)benzoic acid,C13H14N2·C15H12O5,has been synthesized and characterized by single-crystal X-ray diffraction.The compound crystallizes in monoclinic,space group P21 /c with a = 11.639(4),b = 9.808(3),c = 20.854(6),β = 91.242(7)°,V = 2380.0(13)3,C28H26N2O5,Mr = 470.51,Dc = 1.313 g/cm3,μ(MoKα) = 0.091 mm-1,F(000) = 992,Z = 4,the final R = 0.0677 and wR = 0.1477 for 4175 observed reflections(I > 2σ(I)).Intermolecular N H···O hydrogen bonds link two kinds of components into a one-dimensional chain in [10-1] direction and adjacent chains are further arranged into a two-dimensional network by π···π and C H···π interactions.Investigation of intermolecular interactions and crystal packing via Hirshfeld surface analysis reveals that the close contacts are mainly focused on weak interactions.The theoretical investigations with HF/6-31G(d) method were performed,and its stability,frontier molecular orbital composition and Mulliken charge distribution were also discussed.
