cis-[1,4-Bis(diphenylphosphanyl)butane-κ²P,P′]dichlorido(cyclohexane-1,2-diamine-κ²N,N′)ruthenium(II) dichloromethane monosolvate

In the title compound, [RuCl₂(C₆H₁₄N₂)(C₂₈H₂₈P₂)]·CH₂Cl₂, the Ru^II ion is coordinated in a slightly distorted octahedral environment, formed by two cis-oriented chloride ligands, two cis P atoms of a 1,4-bis(diphenylphosphanyl)butane ligand and two cis-chelating N atoms of a bidentate cyclohexane-1,2-diamine ligand. In the crystal, pairs of molecules form inversion dimers via N—H

Cl hydrogen bonds. In addition, intramolecular N—H

Cl and weak C—H

Cl, C—H

N, N—H

π and C—H

π hydrogen bonds are observed. One of the Cl atoms of the solvent molecule is disordered over two sites with refined occupancies of 0.62 (1) and 0.38 (1).

Comment top

Diphosphine compounds as chelate ligands have played a very important role in the design and development of metal complex-mediated catalysis (Lindner, Mayer et al., 2003; Noyori, 1994, 2003). The chelating effects of diphosphine ligands decreases the number of isomers in complexes which decomplicates their structures (Ohkuma et al., 2002; Lindner et al., 2005). Many mixed diamine/diphosphine/ruthenium(II) complexes have been synthesized and characterized for their applications in the field of asymmetrical catalytic hydrogenation, photolysis and bioinorganic chemistry (Noyori & Ohkuma, 2001; Lindner, Warad et al., 2003).

In this work, we report the synthesis and crystal structure of the title complex. The complex cis-[RuCl₂(chd)(dppb)] is in full cis form (Fig. 1) with a solvent molecule of dichloromethane. The Ru^II ion is in a slightly distorted octahedral environment with a five-membered (chd) ring coordinating via N1 and N2, a seven-membered (dppb) ring coordinating via P1 and P2 as well as two Cl atoms. In the seven-membered ring of dppb the P—Ru—P angle is larger than the ideal value for perfectly octahedral. The 1,2-cyclohexanediamine ring also enforces distortion of the N—Ru—N angle [79.89 (13)°] while the Cl–Ru–Cl angle is closer to ideal [90.73 (4)°]. One Cl atom of the CH₂Cl₂ solvent is disordered over two positions with a site-occupancy ratio of 0.62 (1):0.38 (1). The molecular conformation and the crystal packing show various intra and intermolecular contacts of the types N–H···Cl, C–H···Cl and C–H···N (Table 1 and Fig. 2). The molecule and crystal structure are further stabilized by intramolecular N–H···π and intermolecular C–H···π interactions (Table 1). The values of these interactions are similar to those observed in other ruthenium complexes of the same type (Warad, 2007, 2010).

Experimental top

1,2-cyclohexanediamine (0.21 mmol) was dissolved in 10 ml of dry dichloromethane and the resultant solution was added drop-wise to a stirred solution of (RuCl₂(dppb)PPh₃) complex (0.20 mmol) dissolved in 10 ml of dry dichloromethane. The reaction mixture was stirred for 5 min at room temperature under inert atmosphere resulting in a change in color from green to light yellow. The resulting yellow solution was concentrated by vacuum to 1 ml followed by addition of 30 ml of diethyl ether to cause desired complex formation as precipitation. The resulting precipitate was collected and recrystallized from dichloromethane/diethyl ether and obtained in analytically pure form.

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.

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.
