The preparation of Cc-monosubstituted closo and nido carborane derivatives, mono-, di and tetraiodinated is reported. Some of these mono-to poly-iodinated nido carboranes are studied in terms of the acidity of the open face bridging proton, their chemical shift position in the H-1 NMR, and the lesser tendency to eta(5)-coordination in parallel to a larger number of iodo groups.
