In the mononuclear title complex, [Ag(C10H6N4)2]PF6, two κ2N,N′-chelating 5-(pyridin-2-yl)pyrazine-2-carbonitrile ligands surround the AgI atom, forming a distorted N4 tetra­hedral coordination geometry. The mononuclear units are inter­connected through ππ inter­actions [centroid–centroid distances = 3.801 (2) and 3.979 (3) Å] and the hexa­fluoridophosphate anions are embedded within the inter­stices. C N⋯π inter­actions [N⋯centroid = 3.519 (2) Å] and C—H.⋯N hydrogen-bonding inter­actions also occur.

Comment top

The coordination chemistry of pyridyl based ligands has intensively developed in the passed decades (Boudalis et al., 2003; Dunne et al., 1997; Wang et al.,2009).The devious rigid and/or flexible pyridyl based ligands were designed and synthesized to construct many fancy coordination frameworks (Huang et al. 2007). Herein, we report the structure of one new silver(I) complex ([Ag(C10H6N4)2]PF6) derived from 5-(2-pyridyl)pyrazine-2-carbonitrile, a rigid ligand featuring a 2-cyanopyrazinyl group at the 2-pyridyl carbon atom (Scheme 1).

As shown in Fig.1,two κ2 N:N chelating 5-(2-pyridyl)pyrazine-2-carbonitrile ligands surround the AgI center to form a distorted N4-tetrahedral coordination geometry. The Ag—N bond lengthes lie within the range of 2.289 (2)-2.472 (2)Å, with the Ag1—N5 being slight longer than the others, comparable to these in [Ag(C10H6N4)2]BF4 (2.196 (2)-2.685 (2) Å), a similar complex of 5-(2-pyridyl)pyrazine-2-carbonitrile reported (Wang et al. 2010). The two hetero rings of one 5-(2-pyridyl)pyrazine-2-carbonitrile exhibit a dihedral angle of 29.07 (1)°, while in the other one ligand the value is 5.50 (1)°. Such two chelating ligands are almost in an orthogonal orientation, which is remarkablely different from that an anti-relationship in [Ag(C10H6N4)2]BF4 reported by us (Wang et al. 2010). Two mononuclear units arranged in an invert center are interconnected through π(pyrazinyl)···π(pyrazinyl) (Cg1···Cg1i = 3.453 (2) Å, Cg1 = N5-C16-C17-N6-C19-C18 ring, i: -x+1, -y+2, -z+1) and C20N8(cyano)···π(pyridyl) interactions (Table 2) to form a dimeric unit. Along the a axis, the dimeric units are stacked and interconnected via C11—H11A···N7iv(cyano) interaction (Table 1), leading to a column motif. Along the [010] direction, the column motifs interconnect through π(pyridyl)···π(pyridyl) (Cg2···Cg2ii = 3.801 (2) Å, Cg2 = N4-C11-C12-C13-C14-C15 ring, ii: -x+1, -y+1, -z+1) interaction (Table 2), forming a lay in the abplane. Along [001] direction, the formed layers are stacked, and π(pyridyl)···π(pyridyl) interactions (Cg3···Cg3iii = 3.979 (3) Å, Cg3 = N1-C1-C2-C3-C4-C5, iii -x+1, -x+2, -x+2) occur to help to stablize the whole supramolecular structure with the hexafluorophosphate embedded within the interstices.

Experimental top

The ligand 5-(2-pyridyl)-2-cyanopyrazine ligand was obtained commercially. The ligand (18.1 mg, 0.2 mmol) and AgPF6 (26 mg, 0.1mmol) were mixed and dissolved in 5 ml solvent of methanol (3 ml) and acetonitrile (2 ml). After stirring at room temperature for 4 hours, the resulted solution was filtrated, and the clear solution was kepted in air for slow evaporation. After about one week, the colorless block-like crystals were deposited (32.7 mg, 53% yeild).

Refinement top

All the H atoms were discernible in the difference electron density maps. Nevertheless, the hydrogen atoms were placed into idealized positions and allowed to ride on the carrier atoms, with C—H = 0.93 Å and Uiso(H) = 1.2Ueq(C).

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.
