Cyclic alkyl(amino) carbene (cAAC)-supported phosphaalkenides (cAAC![[double bond, length as m-dash]](https://www.rsc.org/images/entities/char_e001.gif)
P)− have been employed as ligands for the isolation of two atomically precise mixed valence paramagnetic AgI/012Cl3, and AgI/010, nano-clusters [(Me2-cAACP)6Ag12Cl3] (2), and [(Me2-cAACP)6Ag10](NTf2)2 (4). 2 and 4 have been structurally characterized by single-crystal X-ray diffraction revealing the presence of three Ag0 atoms, nine AgI ions (2); and two Ag0 atoms, eight AgI ions (4), respectively. The clustering inorganic unit Ag12Cl3 in 2 has been found to be surrounded by six mono-anionic μ3-cAACP moieties having 3-bar symmetry. 2 and 4 have been studied by cyclic voltammetry, UV-vis, ESI-MS, XPS, EPR spectroscopy, and DFT calculations.
