(4-Chlorobenzoato)bis(5-methyl-2-pyridylamine)silver(I)

Abstract top

The title compound, [Ag(C7H4ClO2)(C6H8N2)2], is a mononuclear silver(I) complex. The AgI atom is three-coordinated by two pyridine N atoms from two 5-methylpyridin-2-ylamine ligands and by one O atom of a 4-chlorobenzoate ligand, forming a distorted T-shaped coordination. In the crystal structure, the molecules are linked through intermolecular N-H...O hydrogen bonds, forming chains running along the b axis.

Comment top

Silver(I) complexes with carboxylate ligands and amine compounds have been widely investigated due to their versatile structures (Odoko et al., 2007; Li et al., 2007; Jones et al., 2006; Bi et al., 2002). We report herein the crystal structure of the title silver(I) complex.

The title compound is a mononuclear silver(I) complex (Fig. 1). The AgI atom is three-coordinated by two pyridine N atoms from two 5-methylpyridin-2-ylamine ligands and by one O atom of a 4-chlorobenzoate ligand, forming a distorted T-shaped coordination, the distortion being caused by the weak coordination of the carboxylate O atom (Ag1—O1 = 2.647 (2) Å, Table 1). The Ag—N bond lengths (Table 1) are comparable with the values observed in other silver(I) complexes (Kristiansson, 2000; Wang & Okabe, 2004; Sailaja et al., 2001; Khan et al., 2005; Deng et al., 2004).

In the crystal structure, the molecules are linked through intermolecular N—H···O hydrogen bonds (Table 2), forming chains running along the b axis (Fig. 2).

Experimental top

Ag2O (0.1 mmol, 23.2 mg) and 4-chlorobenzoic acid (0.1 mmol, 15.6 mg) were dissolved in an ammonia solution (10 ml, 30%), and the mixture was stirred for 20 min at room temperature. To the above mixture was added with stirring a methanol solution (3 ml) of 5-methylpyridin-2-ylamine (0.2 mmol, 21.6 mg). The final mixture was stirred for 30 min at room temperature. The resulting clear colourless solution was kept in dark for 12 d, yielding colourless block-shaped crystals.

Refinement top

Atoms H2A, H2B, H4A and H4B were located in a difference Fourier map and refined isotropically, with N—H and H···H distances restrained to 0.90 (1) Å and 1.43 (2) Å, respectively. Other H atoms were placed in idealized positions and constrained to ride on their parent atoms, with C—H distances in the range 0.93–0.96 Å, and with Uiso(H) = 1.2 or 1.5Ueq(C).

Special details top

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