In the title salt, [Pd(C10H8N2)(C6H6NO)2](PF6)2, the PdII atom is in a slightly distorted square-planar coordination environment by N atoms derived from two 4-pyridine­carboxamide ligands, in a cis disposition, and a chelating 2,2′-bipyridine mol­ecule. The monodentate ligands are nearly orthogonal to each other [dihedral angle = 85.7 (5)°] and to the PdN4 plane [dihedral angles = 79.3 (3) and 78.7 (3)°]. The amide O atoms lie to opposite sides of the PdN4 plane. The most notable feature of the crystal packing is a linear supra­molecular chain orientated approximately along [310] and formed via 16-membered {...HNCO}4 motifs. These are connected into a three-dimensional network by amide–H...O, F inter­actions. Both PF6 anions are disordered over two positions of equal occupancy in respect of the F atoms.

Comment top

Carboxamides have been used for the synthesis of supramolecular structures due to their ability to hydrogen bond as shown by Sun et al. (2011) and Moncol et al. (2007). With that in mind we sought to crystallize palladium(II) complexes with 4-pyridinecarboxamide ligands, similar to those created by Galstyan et al., (2011), Fujimura et al. (2004) and Qin et al. (2001). The title compound can be synthesized by the reaction of the 2,2'-bipyridine palladium(II) metal centre with the 4-pyridinecarboxamide ligand or by the palladium-catalyzed hydration of the 2,2'-bipyridine palladium(II) 4-cyanopyridine analog complex in a similar reaction to the one reported by Sanchez et al. (2000).

The complex cation of the title compound, Fig. 1, features a square planar palladium(II) centre with a cis disposition of the N-bound 4-pyridinecarboxamide ligands. No systematic trends are evident in the Pd—N bond lengths (Table 1). The 4-pyridinecarboxamide ligands are almost orthogonal to each other, the dihedral angle being 85.7 (5)°, and to the PdN4 plane with dihedral angles of 79.3 (3) [N1-ligand] and 78.7 (3)°; a similar situation was found in the BF4- analogue (Qin et al., 2001). Each of the amide groups lies out of the plane of the pyridyl ring to which it is connected as seen in the C2—C3—C6—O1 and C8—C9—C12—O2 torsion angles of -166.0 (8) and 171.5 (8)°, respectively. The 2,2'-bipyridine ring is almost planar the dihedral angle between the pyridyl rings being 4.7 (4)°. The amide-O atoms lie to opposite sides of the PdN4 plane.

A detailed analysis of the crystal packing is not possible owing to the disorder in the two PF6- anions. However, the most notable feature of the crystal packing is a supramolecular chain orientated approximately along [3 1 0] arising from centrosymmetric 16-membered {···HNCO}4 synthons constructed by four interacting amide groups (Fig. 2 and Table 2). A three-dimensional architecture arises from additional amide-H···O, F interactions (Table 2).

Experimental top

Pd(bpy)(PF6)2 [bpy = 2,2'-bipyridine] was prepared by adding solid AgPF6 to an acetonitrile suspension of Pd(bpy)Cl2 (0.050 g, 0.15 mmol). After being stirred for 2 h, the mixture was filtered to remove AgCl. Isonicotinamide (0.037 g, 0.30 mmol) was added to the Pd(bpy)(PF6)2 solution and the solution was heated at 323 K for 3 h. Crystals were obtained by vapour diffusion of diethyl ether over an acetonitrile solution of the title complex [0.083 g, 85% yield; M.pt: 513 K (dec.), 523 K (melting)].

Refinement top

Ni and C-bound H-atoms were placed in calculated positions (N—H = 0.88 Å and C—H 0.95 Å) and were included in the refinement in the riding model approximation, with Uiso(H) = 1.2Uequiv(carrier atom). Both PF6 anions are disordered over two positions in respect of the F atoms only. The occupancy was assumed to be 1:1 as it could not be refined. The anisotropic displacement parameters of the F atoms were restrained to be nearly isotropic. Two reflections, i.e. (2 0 18) and (0 6 15), were omitted from the final refinement owing to poor agreement.

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.
