1. A method of capturing radioactive iodide, comprising contacting a substance containing a radioactive iodide with a complex comprising
a) a compound of Formula M3(O)Xb[(O2C)—Y—(CO2)]3(Z)c, wherein
M is a transition metal with an oxidation state of +3 or +4;
Y is an optionally substituted aryl or heteroaryl;
X is an anion having 1 or 2 negative charges;
Z is a neutral molecule capable of coordinating to M;
b is 1 or 2;
c is 0 or 1;
and
b) one or more nitrogen-containing functional molecules, wherein said one or more two functional molecules each contain at least two nitrogens, and one of said at least two nitrogens is coordinated to the M.
