Abstract top

In the title compound, [Cu(C7H2N2O7)(C5H5N)(C10H8N2)], the CuII atom is coordinated by two O atoms from a 3,5-dinitrosalicylate ligand, two N atoms from a 2,2'-bipyridine ligand and one N atom from a pyridine ligand in a square-pyramidal geometry. The structure is stabilized by C-H...O hydrogen bonds and [pi]-[pi] interactions between the bipyridine ligands, with a centroid-centroid distance between neighbouring aromatic rings of 3.96 (8) Å.

Comment top

Salicylic acid and its substituted derivatives continue to attract attention because of their versatile coordination modes (Thurston et al., 2004; Valigura et al., 2004; Wang & Okabe, 2004; Zhu et al., 2003) and biological applications (Lemoine et al., 2004). We report here the structure of a CuII complex with 3,5-dinitrosalicylic acid (He et al., 2005; He et al., 2006; Wen et al., 2007).

In the title complex, the CuII atom is bonded to two N atoms from a 2,2'-bipyridine ligand, one carboxylate O atom and one phenolato O atom from a 3,5-dinitrosalicylate ligand (Fig. 1). The coordination of the CuII atom is completed by bonding to a pyridine N atom in the axial direction, giving a square-pyramidal geometry (Table 1). The dihedral angle of the carboxylate group and the aromatic ring in 3,5-dinitrosalicylate ligand is 10.8 (9)°. The two rings in the 2,2'-bipyridine ligand are a little twisted relative to each other, with a dihedral angle of 2.2 (3)°. The adjacent mononuclear units are further connected to each other by C—H···O hydrogen bonds between the 2,2'-bipyridine (or pyridine) ligands and the O atoms from carboxylate and NO2 groups of the 3,5-dinitrosalicylate ligands (Table 2), resulting in an extended three-dimensional structure (Fig. 2). The partially overlapped arrangement indicates π–π interactions between the approximately parallel 2,2'-bipyridine ligands (the contact distances: C12···C17v = 3.45 (7), C11···C13v = 3.55 (6), C10···C14v = 3.55 (7) Å; symmetry code: (v) 1 − x, 1 − y, 2 − z). The centroid–centroid distance of aromatic rings of the neighboring 2,2'-bipyridine ligands is 3.96 (8) Å. The crystal structure is stabilized by C—H···O hydrogen bonds and π–π interactions.

Experimental top

A mixture of Cu(NO3)2·4H2O (0.026 g, 0.1 mmol), 2,2'-bipyridine (0.016 g, 0.1 mmol), 3,5-dinitrosalicylic acid (0.046 g, 0.2 mmol), pyridine (0.1 ml), NaOH (0.008 g, 0.2 mmol) and distilled water (10 ml) was put into a 20 ml Teflon-lined autoclave and then heated at 393 K for 48 h. Green 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, with C—H = 0.93 Å and Uiso(H) = 1.2Ueq(C).
