Metallodendrimers are emerging as a promising class of new materials for a variety of
applications including heterogenizing homogeneous catalysis. 1 They offer a unique set of
properties such as solubility, precise molecular architecture, predetermined chemical
composition, and the ability, due to their nanoscopic size and relative rigidity, to be removed
from solvent streams by crystallization or ultrafiltration methods for recycling. The
introduction of transition metals into dendrimers has been a recent trend and can be …

LIPPERT* The X-ray structure of the compound described as trans-[(NH3) 2Pt (9-MeA-N7)
2](ClO4) 2 ‚H2O (3c) is actually that of trans-[(NH3) 2Pt (9-MeAH-N7) 2](ClO4) 4 ‚2H2O (3a).
Formulas in the abstract (line 2), the Experimental Section (p 4125, right column, line 67),
the caption of Figure 5, and headings of Tables 1 and 3 should be altered accordingly.
Entries in Table 1 should be changed as follows: compd, 3a, C12H26Cl4N12O18Pt, formula …
