Re. Douthwaite et al., [(silox)(2)ReO](2) (silox = (Bu3SiO)-Bu-t) contains a Re equivalent to Re bond and terminal oxo ligands, CHEM COMMUN, (23), 1998, pp. 2591-2592
The preference for terminal rather than bridging {i.e. [(silox)(2)Re](2)(mu
-O)(2)} oxo ligands in C-2 (silox)(2)(O)Re=Re(O)(silox)(2) is electronic, n
ot steric, in origin.
