The title compound, [Ru(CO3)(η6-C6H6){(C6H11)2P(CH2C10H7)}]·3CHCl3, was synthesized by carbonation of [RuCl2(η6-C6H6){(C6H11)2P(CH2C10H7)}] with NaHCO3 in methanol at room temperature. The RuII atom is surrounded by a benzene ligand, a chelating carbonate group and a phosphane ligand in a piano-stool configuration. The crystal packing is consolidated by C—H⋯O and C—H⋯Cl hydrogen-bonding interactions between adjacent metal complexes and between the complexes and the solvent molecules. The contains one metal complex and three chloroform solvent molecules of which only one was modelled. The estimated diffraction contributions of the other two strongly disordered chloroform solvent molecules were substracted from the observed diffraction data using the SQUEEZE procedure in PLATON [Spek (2009). Acta Cryst. D65, 148–155].

At room temperature, a mixture consisting of [RuCl2(η6-C6H6){(C6H11)2P(1-methylnaphthyl)}] (20 mg, 0.034 mmol), NaHCO3(63 mg, 0.34 mmol) and methanol (5 ml) was stirred under argon in a Schlenk tube. The orange suspension changed to a yellow solution. The reaction was completed within 10 min and the solution was filtered over celite. The solvent was removed in vacuo and 18 mg (94%) of a yellow solid was obtained. Crystals suitable for X-ray analysis were grown from a CHCl3/heptane mixture at 245 K. 1H NMR (300 MHz, CDCl3) δ 8.18 (d, J = 8.6 Hz, 1H, naphthyl), 7.88–7.75 (m, 2H, naphthyl), 7.63–7.30 (m, 3H, naphthyl), 7.33 (m, 1H, naphthyl), 5.07 (s, 6H, benzene), 3.55 (d, J = 10.2 Hz, 2H, CH2), 2.14–1.95 (m, 4H, Cy), 1.95–1.79 (m, 4H, Cy), 1.79–1.65 (m, 4H, Cy), 1.67–1.47 (m, 2H, Cy), 1.32–1.01 (m, 8H, Cy). 31P{1H} NMR (121 MHz, CDCl3): δ 42.5.
H atoms were placed in idealized positions with d(C—H) = 0.95 - 1.00 Å (CH), 0.99 Å (CH2) and refined using a riding model with Uiso(H) fixed at 1.2Ueq(C). Contributions of further disordered solvent molecules were removed from the diffraction data with PLATON / SQUEEZE (Spek, 2009). SQUEEZE estimated the electron count in the void volume of 1149 Å3 to be 501; two voids are given. The highest peak in the final difference Fourier map is located 0.86 Å from Ru1 and the deepest hole 0.75 Å from Cl3.
The title compound was prepared in a two step synthesis: In the presence of 60 bar hydrogen, the benzene ruthenium dichloride dimer and the dicyclohexyl(1-naphthoyl)phosphane ligand react to give the [RuCl2(η6-C6H6){(C6H11)2PCH2C10H7)}] complex in 80% yield. Here, the carbonyl group of the ligand is reduced to a methylen unit (Gowrisankar et al., 2014). In the second step the reduced complex was carbonated at room temperature in methanol with 10 equivalent of NaHCO3 to yield the title compound, [Ru(CO3)(η6-C6H6){(C6H11)2PCH2C10H7)}], as a chloroform solvate after recrystallization from a CHCl3/heptane mixture. Related carbonatophosphane ruthenium complexes are known from the literature (Allen et al., 2009; Blosser et al., 2004; Davies et al., 2013; Dell'Amico et al., 2000; Demerseman et al., 2006; Drake et al., 2013).
The
contains one complex and one chloroform solvent molecule (Fig. 1). Contributions of two further strongly disordered solvent molecules (chloroform) were removed from the diffraction data with the SQUEEZE option in PLATON (Spek, 2009). The RuII atom is surrounded by a benzene ligand, a chelating carbonate group and a phosphane ligand (C6H11)2P(CH2C10H7) in a piano-stool geometry. The phosphane ligand is linked through its P atom with a Ru—P bond length of 2.3705 (8) Å; both cyclohexyl rings at the P atom adopt a chair conformation. The molecular structure shows a planar arrangement of the Ru(CO3) fragment (mean deviation of the best plane defined by Ru1, O1, C1, O2, O3 is 0.036 Å). As expected, the exocyclic C—O bond in the Ru(CO3) unit is with 1.242 (4) Å significantly shorter than the two endocyclic C—O bonds (C1—O1 = 1.326 (4) and C1—O2 = 1.309 (4) Å). The complex molecules as well as complex and solvent molecules are linked by C—H···Cl and C—H···O hydrogen bonds (Fig. 2).The 31P-NMR spectrum of the title complex shows a singulett at 42.5 p.p.m., whereas the reduced complex [RuCl2(η6-C6H6){(C6H11)2PCH2C10H7)}] exhibits an upfield shift to 39.1 p.p.m..

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. |

The title compound was prepared in a two step synthesis: In the presence of 60 bar hydrogen, the benzene ruthenium dichloride dimer and the dicyclohexyl(1-naphthoyl)phosphane ligand react to give the [RuCl2(η6-C6H6){(C6H11)2PCH2C10H7)}] complex in 80% yield. Here, the carbonyl group of the ligand is reduced to a methylen unit (Gowrisankar et al., 2014). In the second step the reduced complex was carbonated at room temperature in methanol with 10 equivalent of NaHCO3 to yield the title compound, [Ru(CO3)(η6-C6H6){(C6H11)2PCH2C10H7)}], as a chloroform solvate after recrystallization from a CHCl3/heptane mixture. Related carbonatophosphane ruthenium complexes are known from the literature (Allen et al., 2009; Blosser et al., 2004; Davies et al., 2013; Dell'Amico et al., 2000; Demerseman et al., 2006; Drake et al., 2013).
The asymmetric unit contains one complex and one chloroform solvent molecule (Fig. 1). Contributions of two further strongly disordered solvent molecules (chloroform) were removed from the diffraction data with the SQUEEZE option in PLATON (Spek, 2009). The RuII atom is surrounded by a benzene ligand, a chelating carbonate group and a phosphane ligand (C6H11)2P(CH2C10H7) in a piano-stool geometry. The phosphane ligand is linked through its P atom with a Ru—P bond length of 2.3705 (8) Å; both cyclohexyl rings at the P atom adopt a chair conformation. The molecular structure shows a planar arrangement of the Ru(CO3) fragment (mean deviation of the best plane defined by Ru1, O1, C1, O2, O3 is 0.036 Å). As expected, the exocyclic C—O bond in the Ru(CO3) unit is with 1.242 (4) Å significantly shorter than the two endocyclic C—O bonds (C1—O1 = 1.326 (4) and C1—O2 = 1.309 (4) Å). The complex molecules as well as complex and solvent molecules are linked by C—H···Cl and C—H···O hydrogen bonds (Fig. 2).
The 31P-NMR spectrum of the title complex shows a singulett at 42.5 p.p.m., whereas the reduced complex [RuCl2(η6-C6H6){(C6H11)2PCH2C10H7)}] exhibits an upfield shift to 39.1 p.p.m..
