چکیده
The asymmetric unit of the title compound, 3C(10)H(8)N(2)·2C(7)H(7)NO(2), consists of three mol-ecules of 4,4'-bipyridine (bpy) and two mol-ecules of 3-amino-benzoic acid (bza). Two mol-ecules of bza and two mol-ecules of bpy are connected via O-H⋯N, N-H⋯N and N-H⋯O hydrogen bonds, forming forming infinite double-stranded zigzag chains along the c axis. The third mol-ecule of bpy is linked to the chain by weak C-H⋯O inter-actions. Adjacent chains are linked via π-π inter-actions [centroid-centroid distances = 3.759 (3)-3.928 (3) Å] involving the pyridine rings of bpy mol-ecules, resulting in a sheet-like structure parallel to (100). These sheets are stacked via C-H⋯π inter-actions, resulting finally in the formation of a three-dimensional supra-molecular structure.

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...

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...

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'...
