Treatment of [Rh<SUB>2</SUB>Cp*<SUB>2</SUB>(<I>μ</I>-CH<SUB>2</SUB>)<SUB>2</SUB>(<I>μ</I>-O<SUB>2</SUB>CO)] (Cp* = <I>η</I><SUP>5</SUP>-C<SUB>5</SUB>Me<SUB>5</SUB>) with acetonitrile in aqueous solution followd by addition of KPF<SUB>6</SUB> affords the Rh–Rh complex [Rh<SUB>2</SUB>Cp*<SUB>2</SUB>(<I>μ</I>-CH<SUB>2</SUB>)<SUB>2</SUB>(<I>μ</I>-NHC(=O)Me)][PF<SUB>6</SUB>], which has been characterized by elemental analysis, FAB-MS, <SUP>1</SUP>H and <SUP>13</SUP>C{<SUP>1</SUP>H} NMR spectroscopy, and X-ray crystallography. [Rh<SUB>2</SUB>Cp*<SUB>2</SUB>(<I>μ</I>-CH<SUB>2</SUB>)<SUB>2</SUB>(<I>μ</I>-<I>η</I><SUP>1</SUP>:<I>η</I><SUP>1</SUP>-NHC(=O)Me)][PF<SUB>6</SUB>] is the first example of an amidato complex where the ligand [NHC(=O)Me]<SUP>−</SUP> links the metal–metal site forming a novel type of metallocycle.
