In the cation of the title salt, [Ag(C₁₂H₆N₂O₂)₂](C₇H₃N₂O₇), the Ag^I atom is coordinated in a distorted tetrahedral geometry by four N atoms from two 1,10-phenanthroline-5,6-dione ligands, while the 3,5-dinitrosalicylate anion has only a short contact [2.847 (6) Å] between one of its O atoms and the Ag^I atom. The dihedral angle between the two 1,10-phenanthroline-5,6-dione ligands is 58.4 (1)°. There is an intramolecular O—H⋯O hydrogen bond in the 3,5-dinitrosalicylate anion.

Comment top

The design and construction of supramolecular architectures have received considerable attention in recent years, mostly motivated by their intriguing structural features and potential applications in molecular adsorption, molecular sensing, magnetism, catalysis and non-linear optics (Che et al., 2008). Metal complexes with 1,10-phenantroline-5,6-dione (L) and 3,5-dinitrosalicylic acid as important ligands for the construction of metal-organic supramolecular architectures have been increasingly studied over recent years (Hiort et al., 1993; Onuegbu et al., 2009; Song et al., 2007). We report herein on the crystal structure of the title compound (Fig. 1). The molecular structure of the title compound, is made up of one [AgL₂]⁺ cation and one 3,5-dinitrosalicylate anion. The Ag^I atom is surrounded by four N atoms from two 1,10-phenanthroline-5,6-dione ligands, while the 3,5-dinitrosalicylate ligand is uncoordinated. In the compound the dihedral angle between the phendione ligand A (C1-C12, N1, N2, O1 and O2) and B (C13-C24, N3, N4, O3, and O4) is 58.4 (1)°. The dihedral angle between B and 3,5-dinitrosalicylate ligand C (C25-C31, N5, N6, O5-O11) is 56.1 (2)°. The dihedral angle between A and C is 2.4 (9)°, suggesting that the planes of rings A and C are almost parallel. In addition, in the 3,5-dinitrosalicylate ligand, there is one intramolecular O–H···O hydrogen bond (Fig. 2).

Experimental top

The L ligand was synthesized according to the literature method (Dickeson & Sumers, 1970). The title compound was synthesized under hydrothermal conditions. A mixture of L (0.042 g, 0.2 mmol), 3,5-dinitrosalicylic acid (0.046 g, 0.2 mmol), AgNO₃ (0.034 g, 0.2 mmol) and water (10 mL) was placed in a 25 mL Teflon-lined autoclave and heated for 3 days at 433 K under autogenous pressure. Upon cooling and opening the bomb, yellow block-shaped crystals were obtained, then washed with water and dried in air.

Special details top

Geometry. All esds (except the esd in the dihedral angle between two l.s. planes) are estimated using the full covariance matrix. The cell esds are taken into account individually in the estimation of esds in distances, angles and torsion angles; correlations between esds in cell parameters are only used when they are defined by crystal symmetry. An approximate (isotropic) treatment of cell esds is used for estimating esds involving l.s. planes.

Refinement. Refinement of F² against ALL reflections. The weighted R-factor wR and goodness of fit S are based on F², conventional R-factors R are based on F, with F set to zero for negative F². The threshold expression of F² > 2sigma(F²) is used only for calculating R-factors(gt) etc. and is not relevant to the choice of reflections for refinement. R-factors based on F² are statistically about twice as large as those based on F, and R- factors based on ALL data will be even larger.
