1,1′-Binaphthyl-2,2′-dicarboxylic acid–urea (1/1)
In the title co-crystal, C(22)H(14)O(4)·CH(4)N(2)O, the 1,1'-binaphthyl-2,2'-dicarboxylic acid (BNDA) and urea mol-ecules are connected via a system of hydrogen bonds into a chiral two-dimensional polymeric structure parallel to the (001) plane. As the crystal is centrosymmetric, it consists of alternately stacked BNDA-urea layers of opposite chirality. The urea H atoms trans to the C=O group a...
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 کامل4-Hydroxy-1-oxo-1,2-dihydrophthalazine-6,7-dicarboxylic acid dihydrate
In the crystal structure of the title compound, C(10)H(6)N(2)O(6)·2H(2)O, the OH and NH groups each serve as a hydrogen-bond donor to one acceptor site whereas the water mol-ecules each serve as a hydrogen-bond donor to two acceptor sites. The hydrogen-bonding scheme gives rise to a three-dimensional network.
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 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...
