Analogous copper nanoclusters (Cu 16/17 ) with two electron superatomic and mixed valence copper( ii )/copper( i ) and copper( i )/copper(0) characters

Three in one: Three Cu NCs of three different characters ( e.g. two electron superatomic and mixed-valent Cu II /Cu I and Cu I /Cu 0 ), stabilized in a common Cu 12 S 12 truncated octahedron, are reported.
