[mu]-Pyrazine-2,5-dicarboxylato-bis[chlorido([eta]6-p-cymene)ruthenium(II)] tert-butanol disolvate

Abstract top

A new tert-butanol solvate of [{(iPrC6H4Me)RuCl}2{[mu]-2,5-pyz(COO)2}] (pyz = pyrazine) has been crystallized and structurally characterized. The solvate, [Ru2(C10H14)2(C6H2N2O4)Cl2]·2C4H10O, contains one half-molecule of the ruthenium(II) complex and one molecule of tert-butanol in the asymmetric unit. The complex molecule lies on an inversion centre with the two chlorides trans. In contrast, the previously reported structure was solvent-free. Similar metric parameters are found between the butanol solvate and the solvent-free form and an intermolecular O-H...O hydrogen bond exists between [mu]-pyrazine-2,5-dicarboxylato-bis[chlorido([eta]6-p-cymene)ruthenium(II)] and the tert-butanol molecule.

Comment top

There has been considerable interest in the chemistry of areneruthenium(II) complexes for a variety of purposes. These range from their interesting and varied coordination chemistry (Cadierno et al., 2002; Drommi et al., 1995) including DNA binding studies (Dorcier et al., 2005) to applications in areas including supramolecular chemistry, as highly selective receptors and catalysis (Dann et al., 2006; Ganter, 2003; Grote et al., 2004; Ion et al., 2006). These organometallic ruthenium(II) fragments have also been used in the synthesis of chiral half-sandwich compounds (Ganter, 2003; Pinto et al., 2004). Pyrazine polycarboxylic acids are excellent ligands for metal coordination (Konar et al., 2004; Ma et al., 2004). Complexes of ruthenium(II) with pyrazine carboxylic acids are known and their redox behaviour has been studied by voltammetric methods (Govindaswamy et al., 2007). We report here the molecular structure of a new tert-butanol solvate of the ruthenium(II) complex [{(η6-p-iPrC6H4Me)RuCl}2{µ-2,5-pyz(COO)2}]\. tBuOH 1. The solvent free structure, 2, which contains one molecule with a trans configuration of the two chloro ligands and a second molecule with twofold symmetry that has two chloro ligands disposed in a cis configuration, has recently been reported (Govindaswamy et al., 2007).

The molecular structure of 1 is shown in Figure 1 and shows a typical piano-stool geometry at each ruthenium(II) centre with each metal bonded to an η6-p-iPrC6H4Me arene [Ru—Ccentroid 1.6689 (16) Å], a terminal chloride and a dianionic N,O-chelating pyrazine ligand. The Ru—Cl bond length in 1 [2.3975 (11) Å] is slightly shorter than that in the trans isomer [2.408 (5) Å] of 2 yet similar to the cis isomer [2.388 (3) Å, 2.399 (3) Å]. The Ru—O and Ru—N bond distances in 1 [2.099 (3) Å and 2.097 (3) Å respectively] are similar to those in the cis isomer of 2 [2.083 (10)/2.109 (9) Å and 2.102 (7)/2.074 (7) Å respectively] and with those of other related three-legged piano-stool ruthenium(II) complexes (Carter et al., 1993; Gemel et al., 2000; Lahuerta et al., 1988). The N(1)—Ru(1)—O(2) bite angle in 1 [77.29 (12)°] is broadly as expected for this type of five-membered chelating ligand. The η6-p-iPrC6H4Me arene ring is essentially planar with C—C bond lengths in the range 1.392 (6)–1.435 (6) Å. The Ru complex is hydrogen-bonded to a tBuOH molecule through a strong intermolecular O—H···O interaction.

In summary, we have reported the crystal structure of a new tert-butanol solvate form of [{(η6-p-iPrC6H4Me)RuCl}2{µ-2,5-pyz(COO)2}] 1 that displays very similar bond lengths and angles around the ruthenium(II) coordination sphere to complex 2 recently published (Govindaswamy et al., 2007).

Related literature top

The structure of the solvent-free complex has been reported previously (Govindaswamy et al., 2007) and shows two molecules in the asymmetric unit. One molecule adopts a trans configuration of the two chloro ligands while the second lies on a twofold axis giving the two chloro ligands a cis configuration.

Experimental top

Crystals of compound 1 were obtained unexpectedly from the experimental procedure outlined here. Boronic acid (0.004 g, 0.007 mmol) in warm tBuOH (10 ml) was added dropwise to a solution of [{(η6-p-iPrC6H4Me)RuCl}2{µ-2,5-pyz(COO)2}] (0.023 g, 0.0325 mmol) in CH2Cl2 (10 ml) affording an orange-red solution. The solution was stirred at room temperature for 3 h and the volume was concentrated to 2–3 ml. Suitable X-ray quality crystals of 1 were obtained by slow vapour diffusion of diethyl ether into the concentrated CH2Cl2/tBuOH solution.

Refinement top

H atoms were placed in geometric positions (C—H distance = 0.95 Å for aryl H; 0.98 Å for methine, 1.00 Å for methyl H; and 0.84 Å for O—H) using a riding model. Uiso values were set to 1.2Ueq (C) (1.5Ueq (C/O)for methyl H and OH atoms respectively).

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.
