10,11,12,13-Tetrahydro-4,5,9,14-tetra-azadibenz[a,c]anthracene-benzene-1,4-dicarboxylic acid (2/1).

ABSTRACT: 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 ?-? stacking inter-actions occur between TTBT rings [centroid-centroid distance = 3.570?(3)?Å], leading to a two-dimensional supra-molecular structure in the crystal.

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 structure in the crystal. ...[more]

Benzene-1,4-dicarboxylic acid-N,N-dimethyl-acetamide (1/2).

Project description: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.

Project description: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 is in the centre of a monocapped distorted octa-hedron made up of four O atoms of two chelating benzene-1,4-dicarboxyl-ate anions, one water O atom and two 1,10-phenanthroline N atoms. The metal centres are connected via bis-chelating benzene-1,4-dicarboxyl-ate anions into a zigzag chain structure along [001]. These chains are further connected by O-H?O hydrogen bonds between the water mol-ecules and adjacent carboxyl-ate O atoms. Additional O-H?O hydrogen bonding between the uncoordinated benzene-1,4-dicaboxylic acid mol-ecules along [010] consolidates the structure.

Project description:The title compound, C(17)H(12)N(2), comprises a norbornane unit having a dicyanona-phthalene ring fused on one side. Both cyano groups are twisted slightly out of the plane of the naphthalene ring system [C-C-C-C torsion angle = 1.9 (2)°].

Hexa-kis-(propyl-ammonium) benzene-1,2,4,5-tetra-carboxyl-ate 2,5-dicarb-oxy-benzene-1,4-carboxyl-ate tetra-hydrate.

Project description:The title organic salt, 6C(3)H(10)N(+)·C(10)H(2)O(8) (4-)·C(10)H(4)O(8) (2-)·4H(2)O, contains seven independent entities in the asymmetric unit which comprises three propyl-ammonium cations, two water mol-ecules, half a 2,5-dicarb-oxy-benzene-1,4-carboxyl-ate dianion (H(2)btc(2-)) and half a benzene-1,2,4,5-tetra-carboxyl-ate tetra-anion (btc(4-)), the latter two anions being located about centres of inversion. One of the water mol-ecules is disordered over two positions in a 0.55 (2):0.45 (2) ratio. The combination of mol-ecular ions and water mol-ecules results in an extensive and complex three-dimensional network of hydrogen bonds, the network being made up of nine unique N-H⋯O inter-actions between the ammonium cations and the anions, as well as four unique O-H⋯O inter-actions between the water mol-ecules and the anions.
