چکیده
The asymmetric unit of the title compound, C(10)H(8)N(2)·2C(8)H(8)O(3), contains two 2-meth-oxy-benzoic acid mol-ecules and one 4,4'-bipyridine mol-ecule. The 4,4'-bipyridine mol-ecule is disordered over two positions in a 1:1 ratio. In the crystal, the 2-meth-oxy-benzoic acid and 4,4'-bipyridine mol-ecules are connected by inter-molecular O-H⋯N hydrogen bonds. The dihedral angle between the carboxy group and its attached ring is 26.823 (2)°.

The asymmetric unit of the title compound, 2C(7)H(2)F(4)O(2)·C(10)H(8)N(2), contains one mol-ecule of 2,3,4,5-tetra-fluoro-benzoic acid (tfb) and half of a centrosymmetric 4,4'-bipyridine mol-ecule. Inter-molecular O-H⋯N hydrogen bonds link two tfb mol-ecules and one 4,4'-bipyridine mol-ecule into a trimer. Weak inter-molecular C-H⋯F inter-actions assemble these trimers into a three-dimensional...

The title compound, C(10)H(8)N(2)·2C(7)H(5)NO(4),was obtained unintentionally as the harvested product of the hydro-thermal reaction between Co(OAc)(2)·4H(2)O and 4,4'-bipyridine in the presence of 3-nitro-phthalic acid. In the reaction, 3-nitro-phthalic acid is transformed into 3-nitro-benzoic acid by an in situ deca-rboxylation reaction, in which the carboxyl-ate group is not deprotonated and...

In the title compound, 2C(8)H(6)O(4)·C(10)H(8)N(2), the 4,4'-bipyridine mol-ecule is located on an inversion centre. In the crystal structure, strong inter-molecular O-H⋯N hydrogen bonds between the terephthalic acid and 4,4'-bipyridine mol-ecules lead to the formation of chains with graph-set motif C(2) (2)(8) along the diagonal of the bc plane.

The hydro-thermal reaction of cobalt nitrate with 4,4'-bipyridine and 3-nitro-benzoic acid lead to the formation of the title complex, [Co(C(7)H(4)NO(4))(2)(C(10)H(8)N(2))(2)](n). In the crystal structure, the Co(II) atoms are coordinated by two terminal carboxyl-ate anions and four 4,4'-bipyridine ligands within slightly distorted octa-hedra. The Co(II) atom and one of the two independent 4,4'...

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 bipyr...
