Atomically
precise copper nanoclusters (NCs) are of immense interest
for a variety of applications, but have remained elusive. Herein,
we report the isolation of a copper NC, [Cu25H22(PPh3)12]Cl (1), from the reaction
of Cu(OAc) and CuCl with Ph2SiH2, in the presence
of PPh3. Complex 1 has been fully characterized,
including analysis by X-ray crystallography, XANES, and XPS. In the
solid state, complex 1 is constructed around a Cu13 centered-icosahedron and formally features partial Cu(0)
character. XANES of 1 reveals a Cu K-edge at 8979.6 eV,
intermediate between the edge energies of Cu(0) and Cu(I), confirming
our oxidation state assignment. This assignment is further corroborated
by determination of the Auger parameter for 1, which
also falls between those recorded for Cu(0) and Cu(I).
