Low-temperature redetermination of trans-cyclohexane-1,2-dicarboxylic acid
The mol-ecule of the title compound, C(8)H(12)O(4), lies on a twofold rotation axis that passes through the mid-points of two opposite C-C bonds of the ring. Carboxyl groups of adjacent mol-ecules are linked by pairs of hydrogen bonds around a centre of inversion; this inter-action gives rise to a chain that runs along [101].
متن کاملBenzene-1,4-dicarboxylic acid–N,N-dimethylacetamide (1/2)
The asymmetric unit of title compound, C(8)H(6)O(4)·2C(4)H(9)NO, contains one half-mol-ecule (an inversion centre in P21/n generates the other half of the molecule) of terephthalic acid (TA) and one mol-ecule of N,N-dimethyl-acetamide (DMAC). The DMAC mol-ecules are linked to TA by strong O-H⋯O hydrogen bonds.
متن کاملPropane-1,3-diaminium–2-carboxypyridine-6-carboxylate–pyridine-2,6-dicarboxylic acid–water (1/2/2/8)
The title proton-transfer compound, C(3)H(12)N(2) (2+)·2C(7)H(4)NO(4) (-)·2C(7)H(5)NO(4)·8H(2)O or (pnH(2))(pydcH)(2).2(pydcH(2))·8H(2)O, was obtained by the reaction of pyridine-2,6-dicarboxylic acid (pydcH(2)) and propane-1,3-diamine (pn) in aqueous solution. Both neutral and monoanionic forms of the diacid are observed in the crystal structure. The negative charge of two monoanions is balanc...
متن کاملrac-7-Oxabicyclo[2.2.1]heptane-2,3-dicarboxylic acid–2-amino-1,3,4-thiadiazole–water (1/1/1)
The title compound, C(8)H(10)O(5)·C(2)H(3)N(3)S·H(2)O, was synthesized by the reaction of 2-amino-1,3,4-thia-diazole with norcantharidin. The crystal structure is stabilized by N-H⋯O, N-H⋯N, O-H⋯O and O-H⋯N hydrogen bonds. In addition, weak π-π inter-actions are observed between symmetry-related thia-diazole ring systems [centroid-centroid distance = 3.9110 (3) Å, inter-planar spacing = 3.4845 Å].
متن کاملThe 1:1 cocrystal of rac-7-oxabicyclo[2.2.1]heptane-2,3-dicarboxylic acid and 2-aminobenzothiazole
In the crystal structure of the title compound, rac-7-oxabicyclo-[2.2.1]heptane-2,3-dicarboxylic acid-2-amino-benzo-thia-zole (1/1), C(8)H(10)O(5)·C(7)H(6)N(2)S, mol-ecules of each component are linked into centrosymmetric dimers by inter-molecular N-H⋯O hydrogen bonds. These dimers are connected by O-H⋯O hydrogen bonds into a chain along the b axis. In addition, π-π inter-actions between aroma...
