Bis(2-hydroxyethanaminium) terephthalate
The asymmetric unit of the title salt, 2C(2)H(8)NO(+)·C(8)H(4)O(4) (2-), comprises one crystallographically independent 2-hy-droxy-ethanaminium cation and one half terephthalate anion. In the crystal, hydrogen bonds involving the hy-droxy and ammonium groups of the cations and the carboxyl-ate O atoms of the terephthalate anions result in the formation of a three-dimensional network structure.
متن کامل2-Ethylimidazolium terephthalate
The asymmetric unit of the title compound, C(5)H(9)N(2) (+)·C(8)H(5)O(4) (-), consists of one protonated 2-ethyl-imidazolium cation and two half terephthalate anions. The anions and cations are linked through N-H⋯O hydrogen bonds while the anions are associated via O-H⋯O inter-actions, resulting in a layered structure. The ethyl group of the cation is disordered over twosites of occupancies 0.8...
متن کاملBis(2-amino-4-methylpyridinium) terephthalate tetrahydrate
In the crystal structure of the title salt, 2C(6)H(9)N(2) (+)·C(8)H(4)O(4) (2-)·4H(2)O, the terephthalate carboxyl-ate groups inter-acts with the 2-amino-4-methyl-pyridinium cations via a pair of N-H⋯O hydrogen bonds, forming an R(2) (2)(8) ring motif. The water mol-ecules form an R(6) (6)(12) ring motif through O-H⋯O hydrogen bonds and these motifs are fused, forming a supra-molecular chain al...
متن کاملCrystal structure of bis(4-allyl-2-methoxyphenyl) terephthalate
The asymmetric unit of the title compound, C28H26O6, contains one half-mol-ecule, with the complete molecule generated by a crystallographic inversion center. The central terephthalate and meth-oxy-benzene rings are approximately perpendicular, making a dihedral angle of 80.31 (5)°. No specific directional contacts are noted in the crystal packing. The terminal vinyl group is disordered over tw...
متن کاملFacile Cellulose Dissolution and Characterization in the Newly Synthesized 1,3-Diallyl-2-ethylimidazolium Acetate Ionic Liquid
A facile cellulose solvent 1,3-diallyl-2-ethylimidazolium acetate ([AAeim][OAc]) with high electrical conductivity has been designed and synthesized for the first time, via a quaternization reaction and ion exchange method. The dissolution characteristics of cellulose in this solvent were studied in detail. Meanwhile, the co-solvent system was designed by adding an aprotic polar solvent dimethy...
