1 Source of materials

The complex was synthesized by modifying the method used before by reduction of hydrated IrCl3 in DMF, which was refluxed for approximately 20 min to give a yellow solution of di-μ-chloro-tetra-carbonyldiiridium(I), [IrCl(CO)2]2. 5 , 6 , 7

The addition of an equivalent of 2-oxopyridine (opoH) to the aforementioned yellow solution followed by addition of ice water to precipitate the dicarbonyliridium(I) complex, [Ir(opo)(CO)2]. The precipitate was filtered off and dried. Red needle crystals were obtained from DCM and benzene.

2 Experimental details

The aromatic H atoms were placed in geometrically idealized positions and constrained to ride on their parent atoms, with fixed C–H distances for aromatic C–H of 0.93 Å (C–H) [U iso(H) = 1.2U eq]. The graphics were obtained using the DIAMOND 4 program with 50 % probability ellipsoids.

3 Comment

Important stages in many catalytic processes, like the carbonylation of methanol, are represented by oxidative addition reactions to metal complexes. 5 Research has shown that in the catalytic cycles of some processes, the oxidative addition phase is the rate-determining step. Consequently, any alteration to this step may dictate the trajectory of the whole catalytic cycle. Owing to the importance of this reaction, a great deal of study has been done on oxidative addition processes to comprehend its kinetic behavior and reactions to both internal and external influences. 6 , 7 There has been much discussion regarding the synthesis of M(I) and M(III) complexes (M = Rh and Ir). Many studies involve the synthesis of the precursor complex [M(L,L′-BID)(CO)2], in which one of the carbonyl ligands may be replaced by tertiary phosphine ligands to form [M(L,L′-BID)(CO)(PX3)], where M represents Rh or Ir, L,L′-BID represents monocharged bidentate ligands with different donor atoms (L,L′) such as O,O′, O,N, O,S, and N,S, and PX3 represents various neutral monodentate tertiary phosphine ligands. 5 , 6 , 7 , 8 , 9 , 10 , 11 , 12 , 13 , 14 , 15 , 16 , 17 , 18 , 19 , 20 , 21 , 22

The 2-oxopyridine (opoH) ligand of the title complex was selected because of its small bite angle, forming a five-membered metallocycle ring when coordinated.

In the title structure, a slightly distorted square planar geometry is observed indicated by the small bite angle of 79.661(2)° for O3–Ir1–O4. The angles between the other atoms of the coordination sphere are affected as a consequence of the small bite angle and have values differing from the ideal 90°; 89.492(2)° for C1–Ir1–C2, 94.903(2)° for C2–Ir1–O4 and 95.942(2)° for C1–Ir1–O3. The Ir1–O3, Ir1–O4, Ir1–C1 and Ir1–C2 bond distances are 2.0372(1), 2.0302(1), 1.8371(1) and 1.8350(1) Å, respectively.
