In the title compound, [Ru(CH3OCS2)2(C18H15P)2], the RuII atom is in a distorted octahedral coordination by two xanthate anions (CH3OCS2) and two triphenylphosphane (PPh3) ligands. Both bidentate xanthate ligands coordinate the RuII atom with two slightly different Ru—S bond lengths but with virtually equal bite angles [71.57 (4) and 71.58 (3)°]. The packing of the complexes is assured by C—H⋯O and C—H⋯π interactions.

A mixture of carbon disulfide CS2 (0.06 ml) and sodium hydroxide KOH (0.003 g, 0.052 mmol) in methanol (30 ml) was stirred a room temperature overnight. Then [RuHCl(CO)(PPh3)3] (0.050 g, 0.052 mmol) was added and the yellow solution was set to reflux for 3 h. Brown crystals suitable for single-crystal X-ray δ: 1.18 (s, 6H, –CH3), 7.0–7.6 (m, PPh3). 31P {1H} NMR (121 MHz, CDCl3) δ: 43.33 (s).
were obtained by slow evaporation of the solvent from a of the title compound.1H RMN (300 MHz, CDCl3)H atoms were included in calculated position (C—H = 0.93 Å for aromatic H, and C—H = 0.96 Å for methyl H), and refined using a riding model with Uiso(H) = 1.2 Ueq of the carrier atoms. 5 badly fitting reflections were omitted from the final refinement.
Complexes containing metal-S and metal-P bonds are of great interest due to their potential role in
(Lu et al., 2003; Wang et al., 2010). In this context, complexes with Ru—S bonds may serve in hydrotreating processes of different fractions of oil and as functional models for Fe—S proteins. Some common sulfur-ligands used to coordinate RuII are dithiolates as dithiocarbamates (R2NCS2-), (ROCS2-) and dithiophosphates ((RO)2PS2-). Examples of Ru(II) complexes with dithiolates reported previously include trans-[Ru(PPh3)2(S2COPr)2], cis-[Ru(PPh3)2(S2COPr)2], cis-[Ru(PPh3)2(S2COiPr)2] (Wu et al., 2009; Bag et al., 1990), cis-[Ru(PPh3)2(S2COEt)2] (Noda et al., 2006) and cis-[Ru(PPh3)2(S2P(OEt)2)2] (Liu et al., 2005).We report here the
of cis-bis(O-Methyldithiocarbonato)-bis(triphenylphosphane)ruthenium (II) cis-[Ru(PPh3)2(S2COMe)2] of which the molecular structure is shown in Fig. 1.The title complex is mononuclear and the ruthenium center is found in a distorted octahedral geometry. The coordination sphere is composed of two triphenylphosphane ligands (PPh3) and two xanthate ligands (S2COMe) arranged in a π], which produce a layer arrangement parallel to the ac plane (Fig. 2).
conformation. The two xanthate ligands coordinate the RuII atom in a bidentated manner with Ru—S distances of 2.4015 (10) and 2.4528 (11) Å for one ligand, and 2.3982 (10) and 2.4425 (11) Å for the other. Such slightly different Ru-S distances for the bidentate xanthate ligand are also found in the analogue compounds cis-[Ru(PPh3)2(S2COiPr)2] (Wu et al., 2009) and cis-[Ru(PPh3)2(S2COEt)2] (Noda et al., 2006). The two bite angles of the chelating xanthate ligands are nearly the same: 71.57 (4)° for S1—Ru1—S2 and 71.58 (4)° for S3—Ru1—S4. The two PPh3 ligands are arranged in a conformation with a P1—Ru1—P2 angle of 100.95 (3)°. The Ru—P distances are 2.3180 (8) Å for Ru1—P1 and 2.3494 (8) Å for Ru1—P2, respectively. These distances are similar to those found in related compounds. There are weak non-covalent interactions [C11—H11···O5 and C40—H40···For complexes with metal-S and metal-P bonds, see: Lu et al. (2003); Wang et al. (2010). For ruthenium complexes with dithiolate ligands, see: Bag et al. (1990); Liu et al. (2005); Noda et al. (2006); Wu et al. (2009).

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. |

Complexes containing metal-S and metal-P bonds are of great interest due to their potential role in homogeneous catalysis (Lu et al., 2003; Wang et al., 2010). In this context, complexes with Ru—S bonds may serve in hydrotreating processes of different fractions of oil and as functional models for Fe—S proteins. Some common sulfur-ligands used to coordinate RuII are dithiolates as dithiocarbamates (R2NCS2-), xanthates (ROCS2-) and dithiophosphates ((RO)2PS2-). Examples of Ru(II) complexes with dithiolates reported previously include trans-[Ru(PPh3)2(S2COPr)2], cis-[Ru(PPh3)2(S2COPr)2], cis-[Ru(PPh3)2(S2COiPr)2] (Wu et al., 2009; Bag et al., 1990), cis-[Ru(PPh3)2(S2COEt)2] (Noda et al., 2006) and cis-[Ru(PPh3)2(S2P(OEt)2)2] (Liu et al., 2005).
We report here the crystal structure of cis-bis(O-Methyldithiocarbonato)-bis(triphenylphosphane)ruthenium (II) cis-[Ru(PPh3)2(S2COMe)2] of which the molecular structure is shown in Fig. 1.
The title complex is mononuclear and the ruthenium center is found in a distorted octahedral geometry. The coordination sphere is composed of two triphenylphosphane ligands (PPh3) and two xanthate ligands (S2COMe) arranged in a cis conformation. The two xanthate ligands coordinate the RuII atom in a bidentated manner with Ru—S distances of 2.4015 (10) and 2.4528 (11) Å for one ligand, and 2.3982 (10) and 2.4425 (11) Å for the other. Such slightly different Ru-S distances for the bidentate xanthate ligand are also found in the analogue compounds cis-[Ru(PPh3)2(S2COiPr)2] (Wu et al., 2009) and cis-[Ru(PPh3)2(S2COEt)2] (Noda et al., 2006). The two bite angles of the chelating xanthate ligands are nearly the same: 71.57 (4)° for S1—Ru1—S2 and 71.58 (4)° for S3—Ru1—S4. The two PPh3 ligands are arranged in a cis conformation with a P1—Ru1—P2 angle of 100.95 (3)°. The Ru—P distances are 2.3180 (8) Å for Ru1—P1 and 2.3494 (8) Å for Ru1—P2, respectively. These distances are similar to those found in related compounds. There are weak non-covalent interactions [C11—H11···O5 and C40—H40···π], which produce a layer arrangement parallel to the ac plane (Fig. 2).
