1,1':4',1''-Terphenyl-2',5'-dicarb-oxy-lic acid dimethyl sulfoxide-d(6) disolvate.

ABSTRACT: The asymmetric unit of the title solvate, C(20)H(14)O(4)·2C(2)D(6)OS, contains half of the substituted terephthalic acid mol-ecule and one solvent mol-ecule. The centroid of the central benzene ring in the acid mol-ecule is coincident with a crystallographic inversion center. Neither the carboxyl nor the phenyl substituents are coplanar with the central aromatic ring, showing dihedral angles of 53.18?(11) and 47.83?(11)°, respectively. The dimethyl sulfoxide solvent mol-ecules are hydrogen bonded to the carb-oxy-lic acid groups.

5,6-Dimethyl-pyrazine-2,3-dicarb-oxy-lic acid.

Project description:The asymmetric unit of the title compound, C(8)H(8)N(2)O(4), consists of one complete mol-ecule and a second mol-ecule generated by the application of twofold axis. The mean planes of the two carboxyl groups attached to the pyrazine ring at neighboring positions are twisted by 10.8?(1) and 87.9?(1)° in the complete molecule and 43.0?(1)° in the symmetry-generated molecule. The crystal packing features O-H?N hydrogen bonds, which link the mol-ecules into layers along [101].

3-Carbamoyl-2,2-dimethyl-cyclo-pentane-1,1-dicarb-oxy-lic acid.

Project description:In the title compound, C(10)H(15)NO(5), the five-membered cyclo-pentane ring has an envelope conformation, with four atoms lying in a plane (mean deviation = 0.0213?Å), while the fifth atom deviates from this plane by 0.626?(2)?Å. A three-dimensional structure is formed through N-H?O and O-H?O hydrogen bonds between the amide and carb-oxy-lic acid groups and both carb-oxy-lic acid and amide O-atom acceptors.

Biphenyl-4,4'-dicarb-oxy-lic acid N,N-dimethyl-formamide monosolvate.

Project description:Biphenyl-4,4'-dicarb-oxy-lic acid was recrystallized from N,N-dimethyl-formamide (DMF) yielding the title compound, C(14)H(10)O(4)·2C(3)H(7)NO. The acid mol-ecules are located on crystallographic centres of inversion and are hydrogen bonded to DMF mol-ecules. These hydrogen-bonded units form infinite chains although there is no inter-action between the methyl groups of neighboring DMF mol-ecules.

Biphenyl-3,3'-dicarb-oxy-lic acid.

Project description:The asymmetric unit of the title compound, C(14)H(10)O(4), contains one half mol-ecule, the complete mol-ecule being generated by a twofold axis. The two benzene rings form a dihedral angle of 43.11?(5)°. Inter-molecular O-H?O hydrogen bonds link the mol-ecules into one-dimensional zigzag chains. These chains are further connected into two-dimensional supra-molecular layers by weak ?-? stacking inter-actions between neighbouring benzene rings, with centroid-centroid distances of 3.7648?(8)?Å.

4,4'-Bipyridine-pyridine-3,5-dicarb-oxy-lic acid (3/4).

Project description:In the title compound, 3C(10)H(8)N(2)·4C(7)H(5)NO(4), the asymmetric unit contains two mol-ecules of pyridine-3,5-dicarb-oxy-lic acid and one mol-ecule of 4,4'-bipyridine in general positions together with one mol-ecule of 4,4'-bipyridine lying across a centre of inversion, thus giving a 4:3 molar ratio of pyridine-3,5-dicarb-oxy-lic acid to 4,4'-bipyridine. The dihedral angle between the bipyridine rings on general positions is 21.2?(2)°. These mol-ecular units are linked by O-H?N hydrogen bonds forming an extended two-dimensional framework in the crystal.

Benzene-1,2-dicarb-oxy-lic acid-pyridinium-2-olate (1/1).

Project description: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 ratio. In the crystal, O-H?O and N-H?O hydrogen bonds link the mol-ecules into zigzag chains in [-101].

4,5-Dicarb-oxy-naphthalene-1,8-dicarb-oxy-lic anhydride-1,10-phenanthroline (1/1).

Project description:In the crystal structure of the title 1:1 adduct, C(12)H(8)N(2)·C(14)H(6)O(7), the carboxyl groups are involved in inter-molecular O-H⋯O hydrogen bonds, which link the mol-ecules into centrosymmetric dimers. These dimers are further linked by inter-molecular O-H⋯N hydrogen bonds. C-H⋯O inter-actions also occur between the 1,10-phenanthroline (phen) and 4,5-dicarb-oxy-naphthalene-1,8-dicarb-oxy-lic anhydride (H(2)NTC) mol-ecules. In addition, the crystal structure exhibits π-π inter-actions of the phen⋯phen and H(2)NTC⋯H(2)NTC types with centroid-centroid distances of 3.579 (3) and 3.774 (3) Å, respectively.

4-Carbamoylpiperidinium 2-carb-oxy-benzoate-benzene-1,2-dicarb-oxy-lic acid (1/1).

Project description:The asymmetric unit of the title salt adduct, C(6)H(13)N(2)O(+)·C(8)H(5)O(4) (-)·C(8)H(6)O(4), comprises one isonipecotamide cation, a hydrogen phthalate anion and a phthalic acid adduct mol-ecule.

Di-?-chlorido-bis-[(2,2'-bipyridine-5,5'-dicarb-oxy-lic acid-?(2)N,N')chloridocopper(II)] dimethyl-formamide tetra-solvate.

Project description:In the title compound, [Cu(2)Cl(4)(C(12)H(8)N(2)O(4))(2)]·4C(3)H(7)NO, which contains a chloride-bridged centrosymmetric Cu(II) dimer, the Cu(II) atom is in a distorted square-pyramidal 4 + 1 coordination geometry defined by the N atoms of the chelating 2,2'-bipyridine ligand, a terminal chloride and two bridging chloride ligands. Of the two independent dimethyl-formamide mol-ecules, one is hydrogen bonded to a single -COOH group, while one links two adjacent -COOH groups via a strong accepted O-H?O and a weak donated C(O)-H?O hydrogen bond. Two of these last mol-ecules and the two -COOH groups form a centrosymmetric hydrogen-bonded ring in which the CH=O and the -COOH groups by disorder adopt two alternate orientations in a 0.44:0.56 ratio. These hydrogen bonds link the Cu(II) complex mol-ecules and the dimethyl-formamide solvent mol-ecules into infinite chains along [-111]. Slipped ?-? stacking inter-actions between two centrosymmetric pyridine rings (centroid-centroid distance = 3.63?Å) contribute to the coherence of the structure along [0-11].

Project description:In the title compound, {(C(2)H(8)N)(2)[Cd(C(20)H(12)O(4))(2)]·2C(3)H(7)NO}(n), the Cd(II) ion lies on a twofold rotation axis and is in a distorted octa-hedral CdO(6) environment, defined by four O atoms of two ?(2)-coordinated 1,1':4',1''-terphenyl-3,3''-dicarboxyl-ate (DCT) ligands and two O atoms of two ?(1)-coordinated DCT ligands. Both types of DCT ligands act as bridging, forming a one-dimensional polymeric structure propagating parallel to [10].
