摘要：

Rhodium K-edge extended X-ray absorption fine structure (EXAFS) analysis has shown that [{Rh(COMe)I-3(CO)}(2)](2-) exists in tetrahydrofuran solution at -20 degrees C, but fragments above 0 degrees C to [Rh(COMe)I-3(CO)(solv)](-); when solv = MeOH, the solution structure shows a substantial trans influence (0.2 Angstrom) on the Rh-I bond trans to the Rh-COMe group.
