1,8-Bis(2-bromoethoxy)anthraquinone (Chen et al., 1992) (1.92 g, 10 mmol) was added to a solution of 2-((1H-imidazol-1-yl)methyl)pyridine (Chiu et al., 2005) (2.48 g, 20 mmol) in 50 ml of THF. The mixture was refluxed for 48 h. The resulting precipitate was isolated and washed with THF(2 × 5 ml) and was then dissolved in methanol (20 ml). To the aqueous solution was added an excess of NH4PF6 resulting in a yellow precipitation. The yellow solid was collected and washed with water and Et2O and dried under vacuum. The title compound was synthesized from the reaction of a slurry of Ag2O (64 mg, 0.275 mmol) in 10 ml of acetonitrile was treated with the yellow soild (213 mg, 0.50 mmol). The mixture was stirred for 12 h with exclusion of light at 323 K until nearly all Ag2O was dissolved. The filtrate was concentrated to ca 2 ml. Addition of Et2O (20 ml) to the filtrate yielded a yellow solid. Yellow single crystals suitable for X-ray diffraction were obtained by recrystallization from acetonitrile.
H atoms were placed in calculated positions with C—H = 0.93–0.97 Å, and refined in riding mode with Uiso(H) = 1.2Ueq(C), and Uiso(H) = 1.5Ueq(C) for the acetonitrile methyl group. In one of the hexafluorophosphate anions five F atoms were found to be disordered over two sites with occupancies 0.756 (11) and 0.244 (11). The disorder was completed with a combination of PLATON (Spek, 2009) and SHELXL97 (Sheldrick, 2008).
Anthraquinone derivatives have attracted much attention due to their optical and photosemiconducting properties (Mahajan et al., 2001, 2002).
The silver(I) atom is bridged by the pyridyl N-atom from one ligand and two acetonitrile molecules and exhibits distorted T shaped coordination (Table 1, Fig. 1). The imidazole rings make dihedral angles with the attached pyridine ring of 61.07 (15)° and anthraquinone ring of 44.80 (10)°. The carbonyl atoms O2 and O4 are almost coplane with the anthraquinone plane, the dihedral angle between the planes of the C23/C24/C25/O2 and C16/C17/C18/O4 fragments is 1.02 (27)°. (Fig. 1).
The crystal structure is stabilized by π–π interactions between the anthraquinone ring systems of the inversion related molecules, with a Cg3···Cg4i distance of 3.676 (3) Å, [symmetry code i: 1 - x, 2 - y, 2 - z] where Cg3 is the C12—C16/C25 ring centroid and Cg4 is the C16—C18/C23—C25 ring centroid (Fig. 2), and two adjacent molecules are bridged by Ag···π interactions involving the pyridyl rings: [Cg2···Ag1ii = 3.405 Å, (Fig. 2). Cg2 is the N1/C1—C5 ring centroid, symmetry code ii: 1 - x, 1 - y, 1 - z]. The present values are thus outside the range of Ag-centroid distances of 2.89–3.37 Å (Mascal et al., 2000). Besides, the structure is further stabilized by C—H···π intermolecular interactions involving the ethoxy carbon C26 and one of the anthraquinone rings [H26B···Cg3iii = 2.98 Å, C26—H26B··· Cg3iii = 148°, and a weaker contact between one of the acetonitrile donors and the imidazole ring is observed H31B···Cg1iv = 3.38 Å, C31—H31B···Cg1iv = 108°. Cg1 and Cg3 are the centroids of the N2/N3/C7—C9 imidazole rings and C12—C16/C25 anthraquinone rings]. Symmetry code for the two interactions, iii: 2 - x, 2 - y, 2 - z; iv: -x, 1 - y, 1 - z.

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. |

Anthraquinone derivatives have attracted much attention due to their optical and photosemiconducting properties (Mahajan et al., 2001, 2002).
The silver(I) atom is bridged by the pyridyl N-atom from one ligand and two acetonitrile molecules and exhibits distorted T shaped coordination (Table 1, Fig. 1). The imidazole rings make dihedral angles with the attached pyridine ring of 61.07 (15)° and anthraquinone ring of 44.80 (10)°. The carbonyl atoms O2 and O4 are almost coplane with the anthraquinone plane, the dihedral angle between the planes of the C23/C24/C25/O2 and C16/C17/C18/O4 fragments is 1.02 (27)°. (Fig. 1).
The crystal structure is stabilized by π–π interactions between the anthraquinone ring systems of the inversion related molecules, with a Cg3···Cg4i distance of 3.676 (3) Å, [symmetry code i: 1 - x, 2 - y, 2 - z] where Cg3 is the C12—C16/C25 ring centroid and Cg4 is the C16—C18/C23—C25 ring centroid (Fig. 2), and two adjacent molecules are bridged by Ag···π interactions involving the pyridyl rings: [Cg2···Ag1ii = 3.405 Å, (Fig. 2). Cg2 is the N1/C1—C5 ring centroid, symmetry code ii: 1 - x, 1 - y, 1 - z]. The present values are thus outside the range of Ag-centroid distances of 2.89–3.37 Å (Mascal et al., 2000). Besides, the structure is further stabilized by C—H···π intermolecular interactions involving the ethoxy carbon C26 and one of the anthraquinone rings [H26B···Cg3iii = 2.98 Å, C26—H26B··· Cg3iii = 148°, and a weaker contact between one of the acetonitrile donors and the imidazole ring is observed H31B···Cg1iv = 3.38 Å, C31—H31B···Cg1iv = 108°. Cg1 and Cg3 are the centroids of the N2/N3/C7—C9 imidazole rings and C12—C16/C25 anthraquinone rings]. Symmetry code for the two interactions, iii: 2 - x, 2 - y, 2 - z; iv: -x, 1 - y, 1 - z.
