N2 - The “masked“ terminal Zn sulfide, [K(2.2.2‐cryptand][ Me LZn(S)] ( 2 ) ( Me L = {(2,6‐ i Pr 2 C 6 H 3 )NC(CH 3 )} 2 CH), was isolated via reaction of [ Me LZnSCPh 3 ] ( 1 ) with 2.3 equiv of KC 8 in THF, in the presence of 2.2.2‐cryptand, at –78 °C. Complex 2 reacts readily with PhCCH and N 2 O to form [K(2.2.2‐cryptand)][ Me LZn(SH)(CCPh)] ( 4 ) and [K(2.2.2‐cryptand)][ Me LZn(SNNO)] ( 5 ), respectively, displaying both Brønsted and Lewis basicity. In addition, the electronic structure of 2 was examined computationally and compared with the previously reported Ni congener, [K(2.2.2‐cryptand)][ tBu LNi(S)] ( tBu L = {(2,6‐ i Pr 2 C 6 H 3 )NC( t Bu)} 2 CH).
