Treatment of carbonyl(1,2-diphenylpenta-1,3-dien-1-yl-5-ylidene)bis(triphenylphosphane)iridium, [IrCO(—C(Ph)=C(Ph)—CH=CH—CH=)(PPh3)2], with either bromine or iodine produced dibromido(1,2-diphenylpenta-1,3-dien-1-yl-5-ylidene)(triphenylphosphine)iridium(III), [IrBr2{—C(Ph)=C(Ph)—CH=CH—CH=}(PPh3)], (I), and (1,2-diphenylpenta-1,3-dien-1-yl-5-ylidene)diiodido(triphenylphosphane)iridium(III), [IrI2{—C(Ph)=C(Ph)—CH=CH—CH=}(PPh3)], (II), respectively, which are two rare examples of 16-electron metallabenzenes. Structural elucidation of (I) and (II) reveals that these isotypic iridabenzenes are unusual, not only in their electron count, but also in their coordination sphere of the IrIII atom where they contain an apparent open coordination site. The crystal structures of (I) and (II) confirm that the molecules are complexes containing five-coordinated IrIII with only one triphenylphosphine group bound to the iridium atom, unambiguously proving that the molecules are indeed 16-electron, high-oxidation-state iridabenzenes. The coordination geometry of the IrIII atom in both structures can be best described as a distorted square pyramid with the P, two Br (or I) and one C atom in the basal plane and another C atom in the apical position.
1. Chemical context
Metallabenzenes are a rare class of organometallic compounds in which a CH unit is isolobally substituted with a transition metal fragment (Bleeke, 2001; Wright, 2006). Postulated in a seminal paper in 1979 (Thorn & Hoffmann, 1979), metallabenzenes have been shown to be feasible through numerous synthetic methodologies and now claim residence in the third and second row transition metals. Our research has focused on the synthesis and properties of metallabenzenes and their valence isomers using 3-vinyl-1-cyclopropenes as the source for the five-carbon backbone (Landorf & Haley, 2006). In certain instances, the metallabenzenes can undergo to afford η5-Cp complexes (Wu et al., 2007). Although such a pathway has potential synthetic utility, for our studies this represents a deleterious side reaction that hinders an effective, detailed examination of metallabenzenes. Computational work by van der Boom and coworkers suggests that metallabenzenes containing metal atoms with higher oxidation states may be resistant toward the pathway (Iron et al., 2003). This prediction interested us as prior studies have shown that IrI iridabenzenes can be readily oxidized with AgI salts or halogens to generate high IrIII iridabenzenes; hence, we sought to synthesize neutral iridabenzenes of higher as initially demonstrated by Bleeke and coworkers (Bleeke et al., 1997). Herein we report the synthesis and structures of iridabenzenes (I) and (II), two rare examples of high oxidation yet coordinatively unsaturated 16-electron IrIII iridabenzenes.
2. Structural commentary
Compounds (I), [IrBr2(C17H13)(C18H15P)], and (II), [IrI2(C17H13)(C18H15P)], are isotypic. The molecular structures of (I) (Fig. 1) and (II) (Fig. 2) confirm that IrIII is five-coordinated in these complexes with only one triphenylphosphine group bound to the iridium atom, unambiguously proving that the molecules are indeed 16-electron, high-oxidation-state iridabenzenes. The coordination geometry of the IrIII atom in both structures can be best described as a distorted square pyramid with the P1, Br1(I1), Br2(I2) and C1 atoms in the basal plane and the C5 atom in the apical position. The Br1(I1), Br2(I2), P1, C1 fragments are planar within 0.17 Å (Br) and 0.21 Å (I) and the Ir atom is out on 0.22 Å (Br) and 0.24 Å (I) from the average planes of this fragment. The C—C bond lengths in the benzene rings in both structures range from 1.360 (15) to 1.402 (16) Å [average 1.387 and 1.382 Å in (I) and (II), respectively], indicative of bond homogenization and electron delocalization. Both Ir—C bond lengths [1.958 (5), 1.903 (5) Å, and 1.963 (11), 1.913 (12) Å, respectively, for Ir—C1 and Ir—C5 in (I) and (II)] are shorter than typical IrI iridabenzenes (2.01–2.05 Å), reflecting the higher IrIII (Fernández & Frenking, 2007).
Additionally, the iridabenzene ring in both structures significantly deviates from planarity (Zhu et al., 2007); the dihedral angle between the C1–C5 fragments [which are planar within 0.03 and 0.04 Å, respectively, in (I) and (II)] and the C1—Ir1—C5 plane is 17.2 (3)° in (I) and 14.9 (7)° in (II). In both structures the open coordination site is located equatorially to the iridium atom, as manifested by the extremely large Br1(I1)—Ir—C1 bond angle of 158.5 (2) [156.0 (3)]° {cf, Br1(I1)—Ir—C5, 110.5 (2) [113.6 (4)°]}. This site is typically occupied by CO in all of our previous iridabenzene studies, such as (III) (Fig. 3). The steric bulk of the two halogen atoms, the triphenylphosphine group, and the phenyl moiety located on C1 all contribute to the presence of the apparent open coordination site. We did consider the possibility of an H atom or H2 molecule occupying the open coordination site. The distance Ir1⋯H29A (one of the H atoms on the closest phenyl group) in (I) is ca 3.18 Å. This H29A atom is on the opposite side from the C5 atom (the C5—Ir1⋯H29A angle is 147°). If present, the Ir—H distance would be around 1.5–1.6 Å. In such a case, the distance between this H atom and the H29A atom from the phenyl ring should be 1.6–1.7 Å. This distance is too short as a typical H⋯H contact is 2.4 Å. It follows then that if one H atom does not fit, H2 will not either. The displacement parameters of most C atoms in the phenyl rings are elongated perpendicular to the average plane of the Ph rings showing their flexibility or statistical disorder.
3. Supramolecular features
Compounds (I) and (II) are typical molecular crystals without specific supramolecular features. Additionally to in these structures there are some weak C—H⋯X (X = Br, I) interactions with C⋯X distances in the ranges of 3.533 (7)– 3.717 (5) and 3.699 (17)–3.707 (12) Å, respectively, for Br and I (Tables 1 and 2). A fragment of the of (I) is given in Fig. 4, illustrating one such weak interaction.

4. Synthesis and crystallization
Reaction of iridabenzene (Gilbertson et al., 1999), (III) (Fig. 3) with one equivalent of bromine at 195 K produced a dark-brown solution that was warmed to 273 K over a period of 30 min. Recrystallization from acetone at 243 K afforded bluish brown crystals of (I). Similarly, reaction of (III) with iodine at 195 K also produced a dark-brown solution containing (II) which was crystallized in similar conditions to give bluish brown crystals. While (I) and (II) were stable in the solid state for weeks at 243 K without noticeable decomposition, solutions of either of the iridabenzenes degraded rapidly and thus made their complete characterization extremely challenging.

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. |

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. |
