Diaqua-bis(2,2'-biimidazole)zinc(II) 4,4'-di-carboxybiphenyl-3,3'-di-carboxyl-ate.

ABSTRACT: In the title compound, [Zn(C(6)H(6)N(4))(2)(H(2)O)(2)](C(16)H(8)O(8)), the Zn(II) atom, located on an inversion centre, is coordinated by two aqua and two bidentate biimidizole ligands, resulting in a slightly distorted octa-hedral ZnO(2)N(4) geometry. The four N atoms from the two biimidizole ligands lie in the equatorial plane and the two aqua O atoms lie in the axial sites. The biphenyl-tetra-carboxyl-ate anion also lies on an inversion centre. The Zn(II) complex cation and the anion are held together by N-H?O hydrogen bonds, forming a zigzag chain along [21]. The chains are further connected by water mol-ecules via O-H?O hydrogen bonds.

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.

Diaqua-bis-(2,2'-bi-1H-imidazole)-man-ganese(II) benzene-1,4-di-carboxyl-ate.

Project description:The asymmetric unit of the title compound, [Mn(C(6)H(6)N(4))(2)(H(2)O)(2)](C(8)H(4)O(4)), contains one-half each of the centrosymmetric cation and anion. The Mn(II) atom is coordinated by four N atoms [Mn-N = 2.2168?(14) and 2.2407?(14)?Å] from two 2,2'-biimidazole ligands and two water mol-ecules [Mn-O = 2.2521?(14)?Å] in a distorted octa-hedral geometry. Inter-molecular N-H?O and O-H?O hydrogen bonds consol-idate the crystal packing, which also exhibits ?-? inter-actions between five-membered rings, with a centroid-centroid distance of 3.409?(2)?Å.

Dimethyl 2,2'-di-nitro-biphenyl-4,4'-di-carboxyl-ate.

Project description:The title compound, C16H12N2O8, exhibits two near-planar aromatic ester groups with ar-yl-ester dihedral angles of 2.1 (2) and 4.2 (3)°. The dihedral angle between the aromatic rings is 58.0 (1)°. The two nitro groups are tilted slightly from the plane of the aromatic rings, making dihedral angles of 14.1 (1) and 8.2 (2)°. In the crystal, mol-ecules are connected by weak C-H⋯O inter-actions, forming a three-dimensional network.

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.

Poly[bis-(4,4'-bipyridine)(μ(3)-4,4'-dicarboxybiphenyl-3,3'-di-carboxyl-ato)iron(II)].

Project description:In the polymeric title complex, [Fe(C(16)H(8)O(8))(C(10)H(8)N(2))(2)](n), the iron(II) cation is coordinated by four O atoms from three different 4,4'-dicarboxybiphenyl-3,3'-di-carboxyl-ate ligands and two N atoms from two 4,4'-bipyridine ligands in a distorted octa-hedral geometry. The 4,4'-dicarboxybiphenyl-3,3'-di-carboxyl-ate ligands bridge adjacent cations, forming chains parallel to the c axis. The chains are further connected by inter-molecular O-H⋯N hydrogen bonds, forming two-dimensional supra-molecular layers parallel to (010).

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.

catena-Poly[[[tetra-aqua-zinc(II)]-?-4,4'-bipyridine-?N:N'] benzene-1,4-di-carboxyl-ate].

Project description:In the title compound, {[Zn(C(10)H(8)N(2))(H(2)O)(4)](C(8)H(4)O(4))}(n), the Zn(II) atoms, lying on a twofold rotation axis, are bridged by 4,4'-bipyridine ligands, resulting in a linear chain along the b axis. In the chain, the Zn(II) atom adopts a slightly distorted octa-hedral coordination geometry involving four water mol-ecules at the equatorial positions. The noncoordinated benzene-1,4-dicarboxyl-ate anion, which is also located on a twofold rotation axis, bridges adjacent chains through O-H?O hydrogen bonds, forming a three-dimensional supra-molecular network.

Project description:In the title compound, [Zn(C(14)H(11)O(2))(2)(C(10)H(8)N(2))(H(2)O)(2)](n), the Zn(II) ion lies on a crystallographic inversion center and is in a slightly distorted octahedral coordination enviroment. 4,4'-Bipyridine ligands act as bridging ligands, connecting Zn(II) ions into a chain along the b-axis direction. In the crystal structure, these chains are linked by inter-molecular O-H?O hydrogen bonds to form a two-dimensional network parallel to the ab plane.
