Abstract top

In the title compound, [Co(C7H2N2O7)(C10H8N2)2], the CoII atom is coordinated by four N atoms from two 2,2'-bipyridine ligands and two O atoms from a 3,5-dinitro-2-oxidobenzoate ligand, displaying a distorted octahedral coordination geometry. The crystal structure involves C-H...O hydrogen bonds between the 2,2'-bipyridine ligands and the carboxylate and NO2 groups of the 3,5-dinitro-2-oxidobenzoate ligand.

Comment top

Much attention has been paid to metal–salicylate complexes owing to their intriguing structural features and biological applications (Lemoine et al., 2004; Wen et al., 2007a, b; Wen & Xie, 2007; Yin et al., 2004). The assembly process of coordination complexes is highly influenced by lots of factors, such as the structural characteristic of organic ligands, the coordination nature of metal ions, pH value of solution, the metal-to-ligand ratio, counter ions and so on. For example, it has been reported that hydrothermal reactions of Co(CH3COO)2.4H2O, 3,5-dinitro-2-oxidobenzoic acid (3,5-dnsalH2) and 2,2'-bipyridine (2,2'-bipy) at different reaction duration give two neutral isomeric metallomacrocycles, Co4(2,2'-bipy)4(3,5-dnsal)4 (Wen et al., 2007c). We report here the structure of a new CoII complex with 3,5-dnsal ligand (Wen & Liu, 2007; Wen et al., 2007d).

The title complex was synthesized under hydrothermal conditions. The CoII atom is coordinated in a distorted octahedral coordination geometry by two O atoms from a 3,5-dnsal ligand and four N atoms from two 2,2'-bipy ligands (Fig.1 and Table 1). The carboxylate group of the 3,5-dnsal ligand is rotated relatively to the aromatic ring with a dihedral angle of 36.8 (2)°. The two pyridyl rings of the 2,2'-bipy ligand containing N5 and N6 are approximately coplanar, exhibiting a dihedral angle of 2.2 (2)°, while the two pyridyl rings of the other 2,2'-bipy containing N3 and N4 deviate from coplanarity with a dihedral angle of 10.6 (2)°. The adjacent mononuclear complex molecules are further connected to each other by C—H···O hydrogen bonds formed between the 2,2'-bipy ligands and the carboxylate and NO2 groups of the 3,5-dnsal ligand, resulting in a three-dimensional network structure (Table 2 and Fig. 2).

Experimental top

A mixture of Co(NO3)2.4H2O (0.1 mmol), 2,2'-bipyridine (0.2 mmol), 2-hydroxy-3,5-dinitrobenzoic acid (0.2 mmol) and distilled water (10 ml) was put into a 20 ml Teflon-lined autoclave and then heated at 423 K for 72 h. Brown block-like crystals of the title compound suitable for X-ray analysis were collected from the reaction mixture.

Refinement top

H atoms were positioned geometrically and refined as riding atoms, with C—H = 0.93 Å and Uiso(H) = 1.2Ueq(C).
