Iridium(I) dimers with bridging N,N′-di-p-tolylformamidine. X-ray molecular structure of Ir2(μ-p-CH3C6H4NCHN-p-C6H4CH3)(μ-NH-p-C6H4CH3)(C8H14)2

The reaction of [IrCl(COD)]2 with K[CH(N-p- C6H4CH3)2] (K+form−) has been carried out in both neat toluene and in the presence of ButOH. In the first case [Ir(form)(COD)]2 (1) was obtained in good yields. The other reaction follows a somewhat different course with partial alcoholysis of the formamidine ligand and formation of Ir2(μ-form)(μ-NH-p-C6H4CH3)(COD)2 (2). Crystal data for compound 2: space group P21/c, a = 9.389(2), b = 21.083(4), c = 16.810(2) Å, β = 91.54(1)° V=3326(2) Å3, Z = 4, R = 0.0343 for 3707 data with Fo2 > 3σ(Fo2).
