In the title dinuclear iridium(III) complex, [Ir2(C10H15)2(C5H5N2S)2]I2, the iridium(III) atoms are bridged by 2-(aminosulfanyl)pyridine(1−) [(2-py)SNH] ligands in a μ-(2-py)SNH-κ2N(py),N(NH):κN(NH) mode. The dinuclear complex cation lies on a crystallographic inversion center, resulting in a planar Ir2N2 ring with an Ir—N(py) bond length of 2.085 (9) Å and bridging Ir—N(NH) bonds of 2.110 (9) and 2.113 (9) Å. The two (2-py)S units have mutually anti configurations with respect to the Ir2N2 ring

Comment top

Nitrogen-atom transfer is one of the promising synthetic methodologies for nitrogen-containing organic/inorganic compounds (Du Bois et al., 1997; Birk & Bendix, 2003). To this end we are trying to prepare high-valent iridium nitrido (or nitrenido) complexes and are investigating their reactivities at the N atom site (Suzuki et al., 2003; Sekioka et al., 2005; Kotera et al., 2008). In our previous paper (Sekioka et al., 2005) it was reported that photolysis of an acetonitrile solution of [Cp*Ir(2-Spy)(N3)] (2-Spy = 2-pyridinethiolate) resulted in insertion of an N atom derived from the azido ligand into the Ir–N(py) bond to afford [Cp*Ir(1-N-2-Spy)]. The reaction solution containing this complex was mixed with P(OMe)3 and MeI in this order and several yellow crystals of compound (I) were deposited from the mixture, although the yield was very low (ca 2%). The single-crystal X-ray analysis revealed that (I) is an iodide salt of a dinuclear iridium(III) complex bridged by 2-pyridylthioamide(1–), [(Cp*Ir)2{µ-(2-py)SNH}2]I2, as shown in Fig. 1. The H atom of the bridging amide ligand (–NH) could not be located in the difference Fourier map. However, the observation of a ν(NH) band at 3073 cm-1 in the IR spectrum and the good agreement of elemental analysis with the calculated values for the diiodide salt, it is suggested that the bridging N atom is protonated to form the amide(1-) ligand. The mechanism for formation of (2-py)SNH- is unknown at present but it could be a by-product of photolysis of the [Cp*Ir(2-Spy)(N3)] complex, or a N atom (or a NH-group) transfer product from the reaction of the [Cp*Ir(1-N-2-Spy)] complex with P(OMe)3 and MeI.

In compound (I), the N–S and S–C bond lengths of the bridging 2-pyridylthioamido(1–) ligand are 1.747 (9) and 1.73 (1) Å, respectively. 2-Pyridylthioamine [alternatively, 2-pyridinesulfenamide: (2-py)SNH2] was prepared by oxidation of 2-pyridinethiolate by chloramine, and its cobalt(II) and iron(II) complexes as well as their Schiff base derivatives {(2-py)SN=CR1R2} were also synthesized more than 40 years ago (Robinson & Hurley, 1965). However, none of the compounds containing (2-py)SNH2 have been so far characterized by X-ray analysis. The only example of the X-ray structural determination of a 2-pyridinesulfenamide is the N-piperidine derivative, (5-NO2-2-py)SNC5H10 (Brito et al., 2002) in which the N–S and S–C bond lengths are 1.699 and 1.761 Å, respectively. The crystal structures of the related aminyl radicals, (2-py)SN(C6H2Ph2R), have also been reported (Miura et al., 2003) in which the N–S and S–C bond lengths are 1.599 (4)–1.626 (8) and 1.770 (6)–1.781 (10) Å, respectively. Thus, in (I) the N–S bond is relatively longer, while the S–C bond is slightly shorter than those in similar organic compounds.

In the related transition-metal complex containing the 2-pyridylthioamide(1–) derivative, a cobalt(III) complex with tridentate (2-pyS)2N- ligands, [Co{(2-pyS)2N}2]ClO4, has been structurally determined (Nakayama et al., 1999). In this complex the N–S and S–C bond lengths are 1.711 (3)–1.718 (3) and 1.742 (4)–1.747 (4) Å, respectively. Furthermore, a few crystal structures of metal complexes with 2-pyridinesulfonamide {(2-py)SO2NH2} derivatives have been reported (Esquivias et al., 2007; Nanthakumar et al., 1999), but compound (I) is the first example containing coordinated (2-py)SNH- ligand has been characterized by X-ray methods. The Ir–N(py) bond length in compound (I) is 2.085 (9) Å, and the bridging Ir–N(NH) bond lengths are 2.110 (9) and 2.113 (9) Å. As seen in Fig. 1, the (2-py)SNH- ligand adopts a µ-κ2N(py),N(NH):κN(NH) bridging mode. This coordination mode is rare, to our knowledge having precedent in only two 2-pyridylmethylamido (2-pyCHRNH-) complexes (Westerhausen et al., 2002; Wong et al., 2002). For the dinuclear iridium(III) complexes bridged by two amide-N donors, Ishikawa, Arita and coworkers reported the sulfonamido-bridged complexes (Ishiwata et al. 2006; Arita et al., 2008). In their p-MeC6H3SO2NH-bridged dinuclear complex, [(Cp*Ir)2(µ-MeC6H3SO2NH)2], the two Cp* ligands are in mutually syn orientations with respect to the Ir2N2 ring, but in (I) the two Cp* ligands adopt an anti configuration .

Experimental top

A solution of [Cp*Ir(N3)(2-Spy)] (59 mg, 0.12 mmol) in dry acetonitrile (2 cm3) was prepared under a nitrogen atmosphere and photolyzed for 15 h with a high pressure Hg lamp (Riko UVL-100HA) at a temperature below 0 °C, controlled by a Yamato Neocool model BD12. To the resulting dark red solution was added P(OMe)3 (35 µL, 0.30 mmol), the color of the mixture immediately turning to yellowish brown. After allowing the solution to stand at ambient temperature for 18 h, methyl iodide (18.5 µL, 0.30 mmol) was added, and then the mixture was allowed to stand overnight. Several yellow crystals of [(Cp*Ir)2(2-pySNH)2]I2 (I) were deposited from the mixture. Yield: 1.5 mg (2.1%). Anal. Found: C, 31.17; H, 3.54; N, 5.08%. Calcd for C30H40I2Ir2N4S2: C, 31.09; H, 3.48; N, 4.83%. IR (Nujol): ν(NH) = 3073 cm-1.

Refinement top

The H atoms were located geometrically and constrained to ride on their parent atoms with N–H = 0.91 Å and C–H = 0.93–0.96 Å with Uiso(H) = 1.2 Ueq(N or C). The largest peak and deepest hole in the difference Fourier map (3.47 and -3.49 eÅ-3) are located 0.82 and 0.82 Å respectively, from atom Ir1.
