Hexaaqua-cobalt(II) 3,3'-dicarb-oxy-biphenyl-4,4'-dicarboxyl-ate.

ABSTRACT: In the crystal structure of the title compound, [Co(H(2)O)(6)](C(16)H(8)O(8)), both the cation and anion are centrosymmetric. The Co cation displays a CoO(6) octa-hedral geometry formed by six water mol-ecules. In the anion, the two carboxyl groups are oriented at dihedral angles of 4.8?(5) and 10.4?(7)° with respect to the benzene ring. Very strong O-H?O hydrogen bonds between the protonated and deprotonated carboxylate groups occur. Neighbouring cations and anions are connected through O-H?O hydrogen bonds into a three-dimensional supra-molecular structure.

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.

Dimethyl 3,3'-di-meth-oxy-biphenyl-4,4'-di-carboxyl-ate.

Project description:In the title compound, C18H18O6, the biphenyl moiety is twisted with a dihedral angle of 29.11 (10)°. The carbometh-oxy groups form C-C-C-O torsion angles of -18.3 (3) and -27.7 (3)° with the attached rings, as a result of steric hindrances from the nearby meth-oxy groups. In the absence of stacking inter-actions and with no H⋯O contacts shorter than 2.7 Å, the packing is dominated by weaker van der Waals inter-actions.

Dimethyl biphenyl-4,4'-dicarboxyl-ate.

Project description:The asymmetric unit of the title compound, C(16)H(14)O(4), consists of one half-mol-ecule of an essentially planar biphenyl-dicarboxylic acid ester, with the complete molecule generated by an inversion centre. The maximum deviation from a least-squares plane through all non-H atoms occurs for the peripheric methyl groups and amounts to 0.124?(2)?Å. The solid represents a typical mol-ecular crystal without classical hydrogen bonds. The shortest inter-molecular contacts do not differ significantly from the sum of the van der Waals radii of the atoms involved.

Crystal structure of dimethyl 4,4'-di-meth-oxy-biphenyl-3,3'-di-carboxyl-ate.

Project description:In the title compound, C18H18O6, the benzene rings are coplanar due to the centrosymmetric nature of the mol-ecule, with an inversion centre located at the midpoint of the C-C bond between the two rings. Consequently, the methyl carboxyl-ate substituents are oriented in a trans fashion with regards to the bond between the benzene rings. The methyl carboxyl-ate and meth-oxy substituents are rotated slightly out of plane relative to their parent benzene rings, with dihedral and torsion angles of 18.52 (8) and -5.22 (15)°, respectively. The shortest O⋯H contact between neighbouring mol-ecules is about 2.5 Å. Although some structure-directing contributions from C-H⋯O hydrogen-bonding inter-actions are possible, the crystal packing seems primarily directed by weak van der Waals forces.

3,3'-[Biphenyl-4,4'-diylbis(-oxy)]diphthalic acid.

Project description:In the title mol-ecule, C(28)H(18)O(10), the two central benzene rings form a dihedral angle of 31.0?(1)°. In the phthalic acid fragments, the carb-oxy groups in the meta positions are approximately coplanar with the attached benzene rings, being inclined to their planes at 2.7?(1) and 10.3?(1)°, while the carb-oxy groups in the ortho positions are twisted from the benzene ring planes by 83.5?(1) and 75.4?(1)°. In the crystal, O-H?O hydrogen bonds link the mol-ecules into layers parallel to the bc plane. Weak C-H?O hydrogen bonds and ?-? inter-actions between the aromatic rings [centroid-centroid distance = 3.7674?(3)?Å] further consolidate the crystal packing.

Tetra-aqua-diazido-cobalt(II) 3,3'-dicarb-oxy-l-ato-1,1'-ethyl-enedipyridinium.

Project description:The asymmetric unit of the title compound, [Co(N(3))(2)(H(2)O)(4)]·C(14)H(12)N(2)O(4), comprises half of the cobalt(II) complex mol-ecule and a half of the 3,3'-dicarboxyl-ato-1,1'-ethyl-enedipyridinium mol-ecule. The Co(II) atom is located on an inversion centre and hence the complex mol-ecule adopts a centrosymmetric trans-octa-hedral geometry. The zwitterionic organic mol-ecule is also centrosymmetric with the centre of the C-C bond of the ethyl-ene moiety coinciding with an inversion centre. The adduct of metal complex and organic mol-ecule is associated into a three-dimenional network through O-H?O hydrogen bonds.

Project description:In the title compound, 2C(2)H(8)NO(+)·C(14)H(8)O(4) (2-), the dihedral angle between the benzene rings of the dianion is 9.95?(12)°. In the crystal, the cations and anions are linked via inter-molecular O-H?O and N-H?O hydrogen bonds, generating layers lying parallel to (001).

Hexaaqua-magnesium(II) bis-(pyridinium-2,6-dicarboxyl-ate).

Project description:In the title compound, [Mg(H(2)O)(6)](C(7)H(4)NO(4))(2), a single six-coordinate Mg(2+) cation (site symmetry 2/m) is bonded to six water mol-ecules in a distorted octa-hedral geometry. The crystal packing between the complex cation and the zwitterionic organic cation (m symmetry) is stabilized by inter-molecular O-H?O hydrogen bonds and weak inter-molecular C-H?O inter-actions.

Diaqua-bis(2,2'-biimidazole)cobalt(II) 4,4'-dicarboxy-biphenyl-3,3'-di-car-boxylate.

Project description:In the title compound, [Co(C(6)H(6)N(4))(2)(H(2)O)(2)](C(16)H(8)O(8)), the Co(II) cation and the organic anion occupy different crystallographic inversion centres and, as a consequence, the asymmetric unit comprises two half-mol-ecules. The benzene groups are coplanar. The four coordinating N atoms of the two bidentate biimidazole ligands define the equatorial plane of a slightly distorted octa-hedral CoO(2)N(4) geometry, and the water O atoms lie in the axial coordination sites. Translational (a,) and inversion-related symmetry operations link the Co complex mol-ecules and the negatively charged carboxyl-ate anions via inter-molecular N-H?O and O-H?O hydrogen bonds into sheets parallel to (01). The coordinated water mol-ecules connect the sheets through O-H?O hydrogen bonds, forming a three-dimensional framework. In addition, two intra-molecular O-H?O hydrogen bonds are observed between the carboxyl and carboxyl-ate groups.

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.
