2-Phenylacetic acid–(E,E)-4,4’-(hydrazinediylidene)dipyridine (2/1)
The asymmetric unit of the title co-crystal, C(12)H(10)N(4)·2C(8)H(8)O(2), comprises a single mol-ecule of 2-phenyl-acetic acid and half a mol-ecule of 4-pyridine-aldazine as this is situated about a centre of inversion. Mol-ecules are connected into a three component aggregate via O-H⋯N hydrogen bonds. As the carb-oxy-lic acid group is almost normal to the plane through the benzene ring to whi...
متن کامل(E)-2-(2-Fluorobenzylidene)butanoic acid
In the crystal structure of the title compound, C(11)H(11)FO(2), the methine CH forms an intra-molecular hydrogen bond with the carboxyl- O atom. The mol-ecules form dimers through hydrogen bonding between carboxyl- groups. These dimers are linked to each other by C-H⋯O contacts between the benzene and carbonyl groups of adjoining mol-ecules. In addition, there are weak inter-molecular C-H⋯F co...
متن کامل(E)-2-(Cyclohexylmethylene)succinic acid
The title compound, C(11)H(16)O(4), crystallizes with three molecules in the asymmetric unit. The cyclo-hexane ring adopts a chair conformation. Inter-molecular O-H⋯O hydrogen bonds are observed and these help to establish the crystal packing.
متن کاملSynthesis and Molecular Structures of (E)-non-2-enoic Acid and (E)-dec-2-enoic Acid
The molecular structures of (E)-non-2-enoic acid (C9) and (E)-dec-2-enoic acid (C10) are reported. The title compounds were crystallized by slow evaporation of ethanolic solutions at −30 °C. C9 crystallizes in the monoclinic space group P21/c and C10 in the triclinic space group P-1, each with 4 molecules in the unit cell. The unit cell parameters for C9 are: a = 10.6473(4) Å, b = 5.2855(2) Å, ...
متن کاملBenzoic acid–2-{(E)-[(E)-2-(2-pyridylmethylidene)hydrazin-1-ylidene]methyl}pyridine (2/1)
The asymmetric unit of the title cocrystal, C(12)H(10)N(4)·2C(7)H(6)O(2), comprises a single mol-ecule of benzoic acid and one half-mol-ecule of 2-pyridine-aldazine situated about a centre of inversion. The carboxyl group is coplanar with the benzene ring to which it is connected [O-C-C-C = -172.47 (12)°] and similarly, the 2-pyridine-aldazine mol-ecule is planar (r.m.s. deviation of the 16 non...
