Structure of Co-crystals Formation from Imidazolium and Aromatic Ligands
摘要:
In this study, two new co-crystals based on rigid imidazolium ligand (2,2'-((1,1'-biphenyl)-4,4'-diyl)bis(2H-imidazo[1,5-a]pyridine-4-ium) hexafluorophosphate (L)) and 4,4'-bipyridine (Bpy) and benzene (Ben), formulated as L(Bpy)0.5 (co-crystal 1) and L(Ben) (co-crystal 2), were obtained. Crystal data for 1: P1 space group with a=10.921(4), b=16.998(6), c=17.666(6) Å, α=95.720(7), β=104.272(7), γ=93.340(6)°, V=3150.5(19) Å3 and Z=2; and crystal data for 2: monoclinic C2/m space group with a=25.90(2), b=9.631(9), c=6.371(6) Å, β=95.26(2)°, V=1583(2) Å3 and Z=2. Co-crystal 1 was dependent on hydrogen bonds and π…π stacking, while only hydrogen bonds are present in 2. Two new co-crystals were characterized by IR, NMR spectra, thermogravimetric and ultraviolet absorption analyses.
