Abstract
The fac-mer rearrangements in [MX3(CO)3]2− (M = Re, 99Tc) induced by a pincer-type ligand (PNP) and a “halide scavenger” are reported. The reactions of fac-[99mTc(CO)3(OH2)3]+ or [99mTcO4]− in saline both yield mer-[99mTc(PNP)(CO)3]+, the first example of a mer-{99mTc(CO)3}+ type complex. In contrast, reactions with terpyridine (terpy) only gave the facial κ2-terpy complexes with Re and 99Tc.| File | Dimensione | Formato | |
