Crystal structures of eight 3D molecular adducts derived from bis-imidazole, bis(benzimidazole), and organic acids
Cocrystallization of the bis(imidazole)/bis(benzimidazole) with a series of organic acids gave a total of eight molecular adducts with the compositions: (3,6-bis(imidazole-1-yl)pyridazine): (trichloroacetic acid)(2) (1) [(H(2)L1)(2+) center dot (tca(-))(2), L1 = 3,6-bis(imidazole-1-yl)pyridazine, tca(-) = trichloroacetate], (bis(N-imidazolyl)methane): (suberic acid) (2) [(L2) center dot (H(2)suba), L2 = bis(N-imidazolyl)methane, H(2)suba = suberic acid], bis(N-imidazolyl)methane: (3-nitrophthalic acid): 3H(2)O (3) [(H(2)L2)(2+) center dot (3-Hnpa(-))(2) center dot 3H(2)O, 3-Hnpa(-) = 3-nitro hydrogenphthalate], (bis(N-imidazolyl)butane)(0.5): (4-nitrophthalic acid): H2O (4) [(H(2)L3)(0.5)(+) center dot (4-Hnpa(-))(-) center dot (HO)-O-2, L3 = bis(N-imidazolyl)butane, 4-Hnpa(-) = 4-nitro hydrogenphthalate], (1(3-(1H-benzimidazol-1-yl)propy1)-1H-benzimidazole): (3,5-dinitrosalicylic acid) (5) [(HLA) center dot (3,5-dns(-)), L4 = 1-(3-(1H-benzimidazol-1-yl)propy1)-1H-benzimidazole, 3,5-dns(-) = 3,5-dinitrosalicylate], (1-(3(1H-benzimidazol-1-yl)propy1)-1H-benzimidazole): (3-nitrophthalic acid) (6) [(H(2)L4) center dot (3-npa(2-)), L4 = 1(3-(1H-benzimidazol-1-yl)propy1)-1H-benzimidazole, 3-npa(2-)=3-nitrogenphthalate], (bis(N-imidazolyl) butane): (pamoic acid) (7) [(H(2)L3) center dot (pam), pam = pamoate], and (3,6-bis(imidazole-1-yl)pyridazine): (1,5-naphthalenedisulfonic acid) [(H(2)L1)(2+) center dot (nPda)(2-) = 1,5-naphthalenedisulfonate] (8). The eight adducts have been characterized by X-ray diffraction technique, infrared spectrum, and elemental analysis, and the melting points of all adducts were also reported. And their structural and supramolecular aspects are fully analyzed. The result reveals that among the eight investigated crystals both the end ring N in the bis(imidazole) moieties are protonated when the organic acids are deprotonated except 2, and 5, and the crystal packing is interpreted in terms of the strong ionic N-H center dot center dot center dot O H-bond between the imidazolium and the deprotonated acidic groups. Except the N-H center dot center dot center dot N H-bond, the O-H center dot center dot center dot O H-bonds were also found at the salts 3, 4, 5, and 7, salt 5 has the additional N-H center dot center dot center dot N H-bond, the N-H center dot center dot center dot S H-bond was established at 8. Further analysis of the crystal packing of the adducts indicated that a different set of additional CH-O/CH2-O, CH-Cl, CH-pi/CH2-pi, Cl-C, CI-N, O-O, O-pi, OH-pi, and pi-pi associations contribute to the stabilization and expansion of the total 3D frameworks. For the coexistence of the various weak interactions these structures had homo or hetero supramolecular synthons or both. Some supramolecular synthons, such as R-1(2)(4),R-2(2)(7), and R-2(2)(8) usually found in crystals of organic acids with imidazole unit, were again shown to be appeared in constructing most of these H-bond networks.
