Abstract Highly reactive copper‐dihydride clusters, [Cu 15 (H) 2 (S CNR ) 6 (C Ph) ](PF {R = n Bu ( 1 H ), Pr i 3 )}, are isolated during the reaction of 28 {S CN } 12 with ten equivalents phenylacetylene. They found to be intermediates in formation earlier reported two‐electron superatom 13 4 ] + . Better yields obtained by reacting dithiocarbamate sodium salts, [Cu(CH CN) BH − and The presence two hydrides clusters is confirmed synthesis characterization its deuteride analogue (D) , a single‐crystal neutron structure Structural reveals new bicapped icosahedral copper(I) cage encapsulating linear copper dihydride (CuH unit.
