(E)-2-{4-[(Pyridin-2-yl)methylideneamino]phenyl}acetic acid
The title mol-ecule, C(14)H(12)N(2)O(2), forms a dimeric unit linked by a pair of symmetry-equivalent O-H⋯N hydrogen bonds. The aromatic rings are significantly twisted from each other with a dihedral angle of 44.04 (4)°.
متن کاملBenzoic acid–4-{(1E)-[(E)-2-(pyridin-4-ylmethylidene)hydrazin-1-ylidene]methyl}pyridine (2/1)
In the title co-crystal, C(12)H(10)N(4)·2C(7)H(6)O(2), the complete 4-pyridine-aldazine mol-ecule is generated by a crystallographic centre of inversion. In the crystal, mol-ecules are connected into a three component aggregate via O-H⋯N hydrogen bonds. As both the benzoic acid [O-C-C-C torsion angle = 174.8 (2)°] and 4-pyridine-aldazine (r.m.s. deviation of the 16 non-H atoms = 0.041 Å) mol-ec...
متن کامل4-[(E)-2-(Pyridin-2-yl)ethenyl]pyridine–terephthalic acid (2/1)
The title 2:1 co-crystal, 2C12H10N2·C8H6O4, crystallizes with one mol-ecule of 4-[(E)-2-(pyridin-2-yl)ethen-yl]pyridine (A) and one half-mol-ecule of terephthalic acid (B) in the asymmetric unit. In the crystal, the components are linked through heterodimeric COOH⋯Npyridine synthons, forming linear aggregates of composition -A-B-A-B-. Further linkage through weak C-H⋯O and C-H⋯π inter-actions g...
متن کاملCrystal structures of four co-crystals of (E)-1,2-di(pyridin-4-yl)ethene with 4-alkoxybenzoic acids: 4-methoxybenzoic acid–(E)-1,2-di(pyridin-4-yl)ethene (2/1), 4-ethoxybenzoic acid–(E)-1,2-di(pyridin-4-yl)ethene (2/1), 4-n-propoxybenzoic acid–(E)-1,2-di(pyridin-4-yl)ethene (2/1) and 4-n-butoxybenzoic acid–(E)-1,2-di(pyridin-4-yl)ethene (2/1)
The crystal structures of four hydrogen-bonded co-crystals of 4-alk-oxy-benzoic acid-(E)-1,2-di(pyridin-4-yl)ethene (2/1), namely, 2C8H8O3·C12H10N2, (I), 2C9H10O3·C12H10N2, (II), 2C10H12O3·C12H10N2, (III) and 2C11H14O3·C12H10N2, (IV), have been determined at 93 K. In compounds (I) and (IV), the asymmetric units are each composed of one 4-alk-oxy-benzoic acid mol-ecule and one half-mol-ecule of ...
متن کامل(E)-2-(4-Chlorophenoxy)-N′-(pyridin-4-ylmethylidene)acetohydrazide
In the title compound, C14H12ClN3O2, the acyl-hydrazone base [C(=O)-N-N=C] is essentially planar, with an r.m.s. deviation of 0.0095 Å, and makes a dihedral angle of 12.52 (10)°with the pyridine ring. In the crystal, molecules are linked via pairs of N-H⋯O hydrogen bonds, forming inversion dimers with an R2(2)(8) graph-set motif. The dimers are linked via C-H⋯π interactions forming chains along...
