The title complex, (I), was obtained as a by-product from the reaction mixture of [Cp*IrCl2]2, Ph2PC6H4Br (Harder et al., 1991) and nBuLi in THF (which was aimed to prepare [Cp*IrCl(Ph2PC6H4)]), together with the corresponding (bromo)(chloro) and dicholoro complexes, [Cp*IrBrCl(PhPC12H8)].CH2Cl2 (II) and [Cp*IrCl2(PhPC12H8)].CH2Cl2 (III), respectively. The resulting red powdery product was recrystallized from a mixture of dichloromethane and methanol, affording red prismatic crystals. Although the crystal structure analyzed was consistent with the dibromo complex (I), the elemental analyses and the NMR spectra of the bulk sample fit well to the 4:4:1 mixture of the dibromo (I), (bromo)(chloro) (II) and dichloro (III) complexes. Anal. Found: C 43.59, H 3.79%. Calcd for C28H28(Br/Cl)2IrP.CH2Cl2: C 43.44, H 3.77%. 1H NMR (399.7 MHz, 303 K, CD2Cl2): δ 1.34 (d, J = 2.4 Hz, Cp*; I), 1.30 (d, J = 2.4 Hz, Cp*; II), 1.26 (d, J = 2.4 Hz, Cp*; III), 7.22–8.20 (m, Ph—PC12H8). 31P{1H} NMR (202.4 MHz, 303 K, CD2Cl2): δ -17.78 (s; I), -14.64 (s; II), -11.34 (s; III).
The H atoms were located geometrically and constrained to ride on their parent atoms with C—H = 0.95–0.99 Å with Uiso(H) = 1.2Ueq(C). The highest peak and deepest hole in the difference Fourier map are located 0.42 and 0.38 Å, respectively, from atoms Ir1 and Br1.
A large number of iridium(III) phosphine complexes has been characterized by X-ray analysis, while the structural study of the analogous phosphole complexes is limited. In fact, there has been no reports on the crystal structures of iridum(III) phosphole complexes, and only one paper describing the phosphole complex of iridium(I) (Hayashi et al., 1983). Here, we report the crystal structure of iridium(III) complex containing 5-phenyldibenzophosphole, [Cp*IrBr2(PhPC12H8)].CH2Cl2 (Cp* = η5-C5Me5), (I). A perspective drawing of (I) is shown in Fig. 1. The structural parameters of the 5-phenyldibenzophosphole moiety are comparable to those of free ligand (Meehan et al., 1997) and of the other metal complexes (Affandi et al., 1988; Attar et al., 1990; Matsuura et al., 1992; Kessler et al., 1993). The Ir—P bond is 2.2828 (15) Å, which is shorter by 0.04 Å than that of [Cp*IrCl2(PPh3)] (2.324 (3) Å; Le Bras et al., 1997). This would be due to the steric compactness of 5-phenyldibenzophosphole than PPh3. The dibenzophosphole moiety is nearly planar; the P atom is deviated by only 0.081 (7) Å from the least-square plane defined by biphenyl group. In the crystal, the dibenzophosphole planes in the neighboring molecules are stacked with each other (Fig. 2); the closest C···C distances between the planes are ~3.9 Å.

A large number of iridium(III) phosphine complexes has been characterized by X-ray analysis, while the structural study of the analogous phosphole complexes is limited. In fact, there has been no reports on the crystal structures of iridum(III) phosphole complexes, and only one paper describing the phosphole complex of iridium(I) (Hayashi et al., 1983). Here, we report the crystal structure of iridium(III) complex containing 5-phenyldibenzophosphole, [Cp*IrBr2(PhPC12H8)].CH2Cl2 (Cp* = η5-C5Me5), (I). A perspective drawing of (I) is shown in Fig. 1. The structural parameters of the 5-phenyldibenzophosphole moiety are comparable to those of free ligand (Meehan et al., 1997) and of the other metal complexes (Affandi et al., 1988; Attar et al., 1990; Matsuura et al., 1992; Kessler et al., 1993). The Ir—P bond is 2.2828 (15) Å, which is shorter by 0.04 Å than that of [Cp*IrCl2(PPh3)] (2.324 (3) Å; Le Bras et al., 1997). This would be due to the steric compactness of 5-phenyldibenzophosphole than PPh3. The dibenzophosphole moiety is nearly planar; the P atom is deviated by only 0.081 (7) Å from the least-square plane defined by biphenyl group. In the crystal, the dibenzophosphole planes in the neighboring molecules are stacked with each other (Fig. 2); the closest C···C distances between the planes are ~3.9 Å.
