Source of material

[RhCl(CO)2]2 was synthesized by refluxing hydrated RhCl3 (0.1002 g, 0.480 mmol) in 6 cm3 DMF for approximately 30 minutes. 2-Hydroxypyridine N-oxide (hopo) (0.0533 g, 0.480 mmol) was added to the aforementioned yellow solution followed by ice water to precipitate [Rh(hopo)(CO)2]. The precipitate was filtered off and dried. [Rh(hopo)(CO)2] (0.0611 g, 0.227 mmol) was dissolved in 7 cm3 of acetone. Triphenylphosphine (PPh3) (0.0629 g, 0.240 mmol) was added to the aforementioned solution with stirring. Ice water was added dropwise to the solution. A light yellow precipitate was filtered off and dried. Yellow cuboid crystals were obtained from recrystallization in acetone, and a few drops of water were added to enhance crystal growth. IR: νCO = 1961 cm−1. 1H NMR (300 MHz, CDCl3) δ = 8.07 (d, 1J = 6.3 Hz, 1H), 7.91 (dd, 2J = 20.9, 1J = 7.1 Hz, 1H), 7.73–7.59 (m, 1H), 7.58–7.53 (m, 1H), 6.96 (d, 1J = 8.4 Hz, 1H), 6.64 (d, 1J = 8.3 Hz, 1H), 6.51 (t, 1J = 5.6 Hz, 1H), 6.43–6.34 (m, 1H). 13C NMR (101 MHz, CDCl3) δ 0189.01 (dd, 2J = 76.7, 1J = 25.3 Hz), 163.00 (s), 162.63 (d, 1J = 2.8 Hz), 135.78 (d, 1J = 4.2 Hz), 134.74 (t, 1J = 6.4 Hz), 134.30 (d, 1J = 11.8 Hz), 133.31 (s), 133.19 (s), 132.97 (s), 132.70 (d, 1J = 3.0 Hz), 132.16 (s), 132.06 (s), 131.98 (d, 1J = 2.8 Hz), 130.48 (d, 1J = 2.4 Hz), 130.42 (d, 1J = 2.5 Hz), 130.14 (s), 128.53 (d, 1J = 12.1 Hz), 128.23 (d, 1J = 10.7 Hz), 116.36 (s), 116.28 (d, 1J = 1.6 Hz), 110.40 (s), 109.61 (s). 31P NMR (162 MHz, CDCl3) δ 049.26 (d, 1J(PRh) = 177.7 Hz), 48.16 (d, 1J(PRh) = 169.6 Hz).

Experimental details

The H atoms were placed in geometrically idealized positions and constrained to ride on their parent atoms with Uiso(H) = 1.2Ueq(Caromatic). The highest peak is located 0.85 Å from O3 and the deepest hole is situated 0.80 Å from Rh1. The C5 and N1 atoms are disordered in a 57.43 % with the higher attributed to the isomer with PPh3cis to N.

Discussion

One of the CO ligands in the precursor [Rh(BID)(CO)2] complexes [where (BID) represents different monoanionic bidentate ligands such as acetylacetonate [1], 2-pyridinethiolato N-oxide [2], cupferrate [3, 4], neocupferrate [5], 2-oxopyridineN-oxide [6] etc.], may be substituted by tertiary phosphine ligands (PR3) such as PPh3 to form [Rh(BID)(CO)(PR3)] complexes. Generally, this substitution with asymmetrical bidentate ligands might form two isomeric complexes where PPh3 is trans-positioned with respect to the strongest donor atom of the bidentate ligand as the preferred isomer [72]. Various crystallographic studies on [Rh(BID)(CO)(PPh3)] complexes revealed that the reaction between [Rh(BID)(CO)2] with PPh3 gives only one isomer that crystalizes from solution [8, 9]. The only example where both isomers crystalized in the same unit cell has been reported for [Rh(BA)(CO)(PPh3)] complex (BA = benzoylacetonato) [10]. In the title structure the ligands are coordinated to rhodium in a distorted square planar geometry. This distortion of the O1—Rh—O2 bond angle from 90° is caused by the small bite angle of 79.3 (6)° of the five membered ring of the chelate. The bite angles of all bidentate ligands of the type [Rh(BID)(CO)(PPh3)] with such five membered rings are in the range 77–80°, compared to the same type of bidentate ligands with six membered rings displaying bite angles of 86–92° [12]. In the title structure, the presence of two isomers, in a 57.43% ratio, with the principal isomer PPh3cis to the N atom, different from expected is evident from the X-ray diffraction data. Furthermore, it was confirmed by 1H, 13C, and 31P NMR spectra of the complex. The effective cone angle, θE, [13] of 154.52(3)° that is similar to related compounds angles [16]. Weak intramolecular hydrogen bond occurs between C14—H14⋯O2 (2.32(1) Å), as well as weak intermolecular hydrogen bond interaction between C4—H4⋯O1 (2.54(1) Å; −x+1, −y+1, −z+1).
