In the title complex, [Ru(C₁₂H₈N₂)₂(C₅H₆N₂)₂](PF₆)₂, the Ru^II atom is bonded to two α-diimine ligands, viz. 1,10-phenanthroline (phen), in a cis configuration, in addition with with two 4-aminopyridine (4Apy) ligands, resulting in a distorted octahedral coordination geometry. N—H⋯F hydrogen-bonding interactions play an important role in the crystal assembly: 2₁-screw-axis-related complex molecules and PF₆⁻ counter-ions alternate in helical chains formed along the a axis by means of these contacts. N—H⋯π contacts (H⋯centroid = 3.45 Å) are responsible for cross-linking between the helical chains along [001].

Comment top

Herein we describe the crystalline structure of the complex namely, cis-[Ru(C₁₂H₈N₂)₂(C₅H₆N₂)₂](PF₆)₂, (I). The 4Apy complex has shown important photochemical activity toward delivery of 4Apy to the central nervous system ( Sinha & Shrivastava, 2012).

Asymmetric units of complex (I) is shown in Fig. 1. As can be seen in this figure, each Ru atom is coordinated to six nitrogen atoms from four ligand molecules. Compound (I) crystallizes in the noncentrosymmetric orthorhombic space group P2₁cn, with one Ru(II) atom, two 1,10-phenanthroline (phen) ligands, two 4-aminopyridine (4Apy) and two PF₆^- counterions in the asymmetric unit. Contacts of type N—H···F are also responsible for keeping coordinated ligands of (I) in contact with PF₆ counterions (Fig. 2). In the packing of this compound, helical chains are formed along the a axis. 2₁-Screw axis related complex molecules and PF₆ counterions are alternated into these chains, which are assembled through the N4A—H4A1···F1A and N4A—H4A2···F3A contacts. A same NH₂ group belonging to the 4Apy(2) moiety is hydrogen bonding donor in both interactions which have one of the two crystallographically independent PF₆ units as acceptor. The other PF₆ counterion is a hydrogen bonding acceptor from the other amine group of the 4Apy(1) moiety through the N4—H4A···F5 contact. This interaction in association with the non-classical C10A—H10A···F6 hydrogen bonding contributes to assemble the helical chains along the [100] direction. More specifically, PF₆ units acting as hydrogen bonding acceptors through their F5 and F6 atoms are connected to translation related complex molecules of the helical backbone. At last, the other NH₂ hydrogen of the 4Apy(1) moiety is involved in a N—H···π interaction with the π–system of the 4Apy(2) ring. The occurrence of such intermolecular contact is supported on the basis of the moderate separation between H4B and the centroid of the 4Apy(2) ring (labeled as Cg) (3.45 Å). This N4—H4B···Cg interaction is responsible for the cross-linking between helical chains along the [010] direction. Geometric parameters of the classical hydrogen bonding interactions are shown in Table 1.

The complex shows the Ru atom bonded to two a-diimine ligands in a cis configuration with the two 4Apy ligands in the expected distorted-octahedral fashion. The trans N—Ru—N angles (mean values of 176 (2)° (I), deviate slightly from the ideal value of 180°. Corresponding cis angles show similar small deviations from 90°: 90 (6)°. The mean Ru—N(α-diimine) distance [2.07 (1) Å in (I)] is similar to that found in a related coordination complex with the [Ru(bpy)₃)]²⁺ moiety (2.056 Å) (Stoyanov et al., 2002).

In the present structure, the α-diimine coordinated ligands are approximately planar with deviation from the least-square planes less than 2°. The two α-diimine ligands are nearly perpendicular, as indicated by the dihedral angle between their least square planes, 87.43 (9)° in (I).

The dihedral angles do not show any significant distortions in the structure of the complex to relieve the steric hindrance imposed by phenanthroline ligand. Fig. 1 shows a very neat twisted location of the 4Apy ligands with respect to the planes of the phen ligands. The dihedral angles between the least-squares planes calculated through 4Apy and phen ligands are 86.9 (1)° [4Apy(1) and phen(1)] and 79.2 (1)° [4Apy(2) and phen(2)].

Experimental top

The compound (I) was synthesized from the corresponding aquo-complex (Bonneson et al., 1983) cis-[Ru(α-diimine)₂(OH₂)₂](PF₆)₂ [α-diimine = 1,10-phenanthroline (phen)] by reacting the latter with 4-Aminopyridine in 1:1 EtOH/H₂O mixture under nitrogen atmosphere and for 8 h under reflux. A stoichiometric amount of ammonium hexafluorophosphate was added to precipitate the complex. The resulting solid products were crystallized from acetonitrile. Elemental analysis (%) for (I) RuC₃₄H₃₂N₈P₂F₁₂O₂: calculated: C, 41.80, N, 11.48; H, 3.30; found: C, 41.7; N, 11.5; H, 3.13.8; found: C, 38.70; N, 11.80; H, 3.54.

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.
