In the title complex, [RhCl(C44H32OP2)]·CH3OH, the RhI ion is coordinated by a naphthyl group of a partially oxidized 2,2′-bis(diphenylphosphanyl)-1,1′-binaphthyl (BINAP) ligand in a η4 mode, one P atom of the diphenylphosphanyl group and one Cl atom. The P=O group does not interact with the RhI ion but accepts an O—H⋯O hydrogen bond from the methanol solvent molecule.

[Rh(COD)(µ2-Cl)]2 (0.03 g, 0.06 mmol) and BINAP (0.02 g, 0.03 mmol) were dissolved in tetrahydrofuran at room temperature under anaerobic conditions using standard schlenk-techniques. After stirring for 30 min, the solvent was removed under vacuum. The dark red colored residue was recystallized from CH2Cl2 to afford [Rh(BINAP)(µ2-Cl)]2.
[Rh(BINAP)(µ2-Cl)]2 (0.015 g, 0.01 mmol) and MAC (0.219 g, 1 mmol) were dissolved in 15 ml MeOH and stirred for 6 h under hydrogen. Crystals of the title compound were isolated after two days from the reaction solution, which contained residual traces of oxygen. 31P-NMR (300 MHz, THF-d8): δ 55.3 p.p.m. (d, JP—Rh = 198,3 Hz), δ 24.4 p.p.m.
H atoms were placed in idealized positions and refined using a riding model, with C—H = 0.93 and 0.98 (CH), 0.96 (CH3) and O—H = 0.82 (OH) Å and with Uiso(H) = 1.2(1.5 for methyl and hydroxyl)Ueq(C, O).

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. |

Ligand exchange between 1,5-cyclooctadiene (COD) and 2,2'-bis(diphenylphosphanyl)-1,1'-binaphthyl (BINAP, a chiral binaphthyl-based chelating diphosphine) in the complex [Rh(COD)(µ2-Cl)]2 has been investigated by Preetz (2009) and Bunten et al. (2002). When the reaction is carried out at room temperature, either in dichloromethane or toluene, the complex [Rh(BINAP)(µ2-Cl)]2 is formed in 99% yield. The title complex, [Rh(BINAP(O))Cl], containing monooxidized BINAP(O) was isolated from a solution of [Rh(BINAP)(µ2-Cl)]2 and methyl-(Z)-α-acetamidocinnamate (MAC) in MeOH, which contained obviously residual traces of oxygen. The molecular structure of [Rh(BINAP(O))Cl] is shown in Fig. 1.
In the title complex, the RhI atom is η4-coordinated to one of the binaphthyl moieties of the partially oxidized BINAP ligand but not to the O atom. Coordination to O atom is instead observed in the complex [Rh(BINAP(O))(CO)Cl] described by Bunten et al. (2002). This complex has a square-planar geometry with a CO ligand located trans to the O atom. The Rh—P distance of 2.1988 (10) Å in the title complex is by more than 0.1 Å shorter than that in the typical BINAP-rhodium complexes [2.304 (2)–2.335 (2) Å] (Preetz et al., 2010; Tani et al., 1985) and slightly shorter than in [Rh(BINAP(O))(CO)Cl] [2.242 (1) Å]. The Rh—C bond lengths, varying from 2.092 (3) to 2.497 (3) Å, are in the range of the known BINAP-rhodium complexes with benzene (2.226–2.241 Å) (Fischer et al., 2012). The Rh—Cl distance is 2.3222 (15) Å, comparable to that in [Rh(BINAP(O))(CO)Cl] [2.382 (1) Å] (Bunten et al., 2002). An O—H···O hydrogen bond between the methanol solvent molecule and the complex molecule is observed (Table 1).
