Benzene-1,3,5-tricarboxylic acid–pyridinium-2-olate (1/3)
The asymmetric unit of the title compound, C9H6O6·3C5H5NO, contains one benzene-1,3,5-tri-carb-oxy-lic acid mol-ecule (BTA) and three pyridin-2-ol mol-ecules each present in the zwitterion form. In the crystal, these entities are linked through O-H⋯O(-) and N(+)-H⋯O(-) hydrogen bonds, forming sheets parallel to (10-1). These layers contain macrocyclic rings of composition [BTA]2[pyol]6 and with...
متن کاملBenzene-1,2-dicarboxylic acid–pyridinium-2-olate (1/1)
The asymmetric unit of the title compound, C(5)H(5)NO·C(8)H(6)O(4), contains one o-phthalate acid mol-ecule and one pyridin-2-ol mol-ecule, which exists in a zwitterionic form. In the o-phthalate acid mol-ecule, the carboxyl-ate groups are twisted from the benzene ring by dihedral angles of 13.6 (1)° and 73.1 (1)°; the hy-droxy H atom in the latter group is disordered over two positons in a 1:1...
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 کامل10,11,12,13-Tetrahydro-4,5,9,14-tetraazadibenz[a,c]anthracene–benzene-1,4-dicarboxylic acid (2/1)
In the title adduct, 2C(18)H(14)N(4)·C(8)H(6)O(4), the centrosymmetric 1,4-benzene-dicarboxylic acid mol-ecule makes two O-H⋯·N hydrogen bonds to adjacent 10,11,12,13-tetra-hydro-4,5,9,14-tetra-azadibenzo[a,c]anthracene (TTBT) mol-ecules. Aromatic π-π stacking inter-actions occur between TTBT rings [centroid-centroid distance = 3.570 (3) Å], leading to a two-dimensional supra-molecular structur...
متن کاملcatena-Poly[[[aqua(1,10-phenanthroline)cadmium(II)]-μ-benzene-1,4-dicarboxylato] benzene-1,4-dicarboxylic acid hemisolvate]
A new cadmium(II) coordination polymer, {[Cd(C(8)H(4)O(4))(C(12)H(8)N(2))(H(2)O)]·0.5C(8)H(6)O(4)}(n), has been synthesized under hydro-thermal conditions. The asymmetric unit contains one Cd(II) atom, one benzene-1,4-dicarboxyl-ate anion, one 1,10-phenanthroline ligand, one coordinated water mol-ecule and half of an uncoordinated benzene-1,4-dicaboxylic acid solvent mol-ecule. The Cd(II) atom ...
