Disodium dihydrogen pyridine-2,3,5,6-tetra-carboxyl-ate trihydrate.

ABSTRACT: In the title compound, 2Na(+)·C(9)H(3)NO(8) (2-)·3H(2)O, the asymmetric unit consists of two Na(+) cations, one dihydrogen pyridine-2,3,5,6-tetra-carboxyl-ate dianion (H(2)pdtc(2-)) and three water mol-ecules coordinated to the Na(+) cations. The configuration of the anion is stabilized by intramolecular O-H?O hydrogen bonding between vicinal carboxylate/carboxy groups. The Na(+) cations are bridged by the H(2)pdtc(2-) dianions, generating layers extending infinitely in sheets parallel to (001), and further pillared by the water mol-ecule linkers to build up a three-dimensional framework.

catena-Poly[[[tetra-aqua-cobalt(II)]-μ-4,4'-bipyridine-κN:N'] pyridine-3,5-dicarboxyl-ate trihydrate].

Project description:The crystal structure of the title compound, {[Co(C(10)H(8)N(2))(H(2)O)(4)](C(7)H(3)NO(4))·3H(2)O}(n), consists of Co(II) polymeric complex cations, uncoordinated pyridine-3,5-dicarboxyl-ate anions and lattice water mol-ecules. The Co(II) cation is coordinated by two N atoms from two 4,4'-bipyridine ligands and four water mol-ecules in a distorted octa-hedral geometry. The 4,4'-bipyridine ligands bridge Co cations, forming a polymeric chain running along the b axis. The two pyridine rings of the 4,4'-biyridine are twisted to each other by a dihedral angle of 8.95 (9)°. Extensive O-H⋯O hydrogen bonding network is present in the crystal structure.

4,11-Diaza-1,8-diazo-niacyclo-tetra-decane bis-(pyridine-2-carboxyl-ate) dihydrate.

Project description:The asymmetric unit of the title compound, C(10)H(26)N(4) (2+)·2C(6)H(4)NO(2) (-)·2H(2)O, consists of half of a doubly protonated 1,4,8,11-tetra-azacyclo-tetra-decane (cyclam) dication, a pyridine-2-carboxyl-ate anion and a solvent water mol-ecule. The complete dication is generated by a crystallographic centre and adopts an endodentate conformation which may be influenced by intra-molecular N-H?N hydrogen bonding. The carboxyl-ate group of the anion appears to be delocalized on the basis of the C-O bond lengths [1.257?(2) and 1.250?(2)?Å]. In the crystal structure, the components are linked by inter-molecular N-H?O, N-H?N and O-H?O hydrogen bonds.

Tetra-methyl anthracene-2,3,6,7-tetra-carboxyl-ate-tetra-methyl 9,10-dihydro-9,10-dioxoanthracene-2,3,6,7-tetra-carboxyl-ate (1/1).

Project description:In the title co-crystal, C(22)H(16)O(10)·C(22)H(18)O(8), the independent tetra-methyl 9,10-dihydro-9,10-dioxoanthracene-2,3,6,7-tetra-carboxyl-ate, (I), and tetra-methyl anthracene-2,3,6,7-tetra-carboxyl-ate, (II), components occupy separate crystallographic inversion centers. In (II), the dihedral angles between the mean aromatic plane and the two independent carboxyl-ate planes are 41.32 (10) and -38.35 (10)°. The methyl-carboxyl-ate groups of (I) are disordered, with each resolvable into two groups. In the least disordered carboxyl-ate, the apparent angles between the mean aromatic plane and the two partial carboxyl-ate planes [site occupations = 0.510 (3) and 0.490 (3)] are 16.8 (3) and 23.3 (3)°. In the highly disordered group, the apparent angles between the mean aromatic plane and the two partial carboxyl-ate planes [site occupations = 0.510 (3) and 0.490 (3)] are 78.3 (3) and -74.1 (3)°. In addition, this extreme disorder leads to an artificially elongated C(aromatic)-C(carbox-yl) bond.

In the crystal, inversion dimers linked by pairs of C-H?O hydrogen bonds between the tetra-hydro-1-benzothio-phene and the pyridine-4-carboxamide residues generate R(2) (2)(16) loops. There exists positional disorder in three methelene groups of the cyclo-hexane ring and the terminal C atom of the ethyl ester side chain in a 0.691?(14):0.309?(14) occupancy ratio.
