Figure 2.9 (A) Correlation between the average number of C 2 H 4 groups bonded to

iridium when Ir(CO) 2 complexes were treated in flowing C 2 H 4 at 298 K
and 1 bar and (B) normalized white-line intensities of the initially
prepared Ir(CO) 2 complexes characterizing the complexes on various
supports and the frequency of n CO bands of the Ir(CO) 2 complexes
(a higher n CO frequency indicates that the iridium complex is more
electron-deficient). The Ir(CO) 2 complexes were prepared by treating
Ir(C 2 H 4 ) 2 complexes with a pulse of CO in helium at 298 K.
