Trans-2,2'-bipyridinedichloromethyl-1-(phenylimino)-1-(phenylhydrazono)-acetate ruthenium(II) was prepared according to literature procedure (Al-Noaimi et al.,2007) and recrystallized by slowly evaporating a solution of dichloromethane.
The methylyester group has a 0.591 (18):0.409 (18) occupancy disorder over two positions. The disordered atoms were refined isotropically. The O2A—C3A distance was restrained to 1.433 (9) Å. All hydrogen atoms were set to idealized positions and were refined with 1.2 times (1.5 for the methyl group) the isotropic displacement parameter of the corresponding carbon atom.
Ruthenium (II) complexes containing the azoimine (N=N—C=N) functional unit are light-sensitive, redox-active, and efficient colorant materials (Kaim, 2001). This function is π-acidic and has successfully been used to stabilize the low-valent metal redox state. The importance of azoimine chemistry encourages us to develop a new ligand containing an azoimine unit. The new unsymmetrical bidentate ligand, methyl-1-(phenylimino)-1-(phenylhydrazono)-acetate (L), lacks a twofold symmetry axis and on complexation with ruthenium (II), affords a pseudo-octahedral, trans-[Ru(bpy)LCl2] complex. The five membered rings formed by the coordination of azoimine and bpy are planar and have almost equivalent coordination bite-angles N1—Ru—N2 = 75.9 (2)°, and N4—Ru—N5 = 76.6 (2)°, respectively, whereas Cl2—Ru—Cl1 angle is 169.52 (6)°. However, it is interesting to note that the bond lengths of Ru(II) and azoimine N atoms, (Ru—N1) = 2.009 (5) Å and (Ru—N2) = 1.953 (5) (4) Å are significantly shorter than those of Ru(II) and the bpy N atoms, (Ru—N4) = 2.145 (5) Å and (Ru—N5) = 2.123 (5) Å indicated preferential π-bonding of Ru(II) with the azo group.

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. |

Ruthenium (II) complexes containing the azoimine (N=N—C=N) functional unit are light-sensitive, redox-active, and efficient colorant materials (Kaim, 2001). This function is π-acidic and has successfully been used to stabilize the low-valent metal redox state. The importance of azoimine chemistry encourages us to develop a new ligand containing an azoimine unit. The new unsymmetrical bidentate ligand, methyl-1-(phenylimino)-1-(phenylhydrazono)-acetate (L), lacks a twofold symmetry axis and on complexation with ruthenium (II), affords a pseudo-octahedral, trans-[Ru(bpy)LCl2] complex. The five membered rings formed by the coordination of azoimine and bpy are planar and have almost equivalent coordination bite-angles N1—Ru—N2 = 75.9 (2)°, and N4—Ru—N5 = 76.6 (2)°, respectively, whereas Cl2—Ru—Cl1 angle is 169.52 (6)°. However, it is interesting to note that the bond lengths of Ru(II) and azoimine N atoms, (Ru—N1) = 2.009 (5) Å and (Ru—N2) = 1.953 (5) (4) Å are significantly shorter than those of Ru(II) and the bpy N atoms, (Ru—N4) = 2.145 (5) Å and (Ru—N5) = 2.123 (5) Å indicated preferential π-bonding of Ru(II) with the azo group.
