    Fragmentation reactions of organotetrel chalcogenide heteroadamantane-type clusters [(PhT) 4 E 6 ] (T/E = Si/S ( 1 ); Si/Se; Sn/S, and Sn/Se) by addition of the corresponding sodium chalcogenide yield salts of the general formula Na 3 [PhTE 3 ], with T/E = Si/S ( 2 ); Si/Se ( 3 ); Sn/S ( A ); Sn/Se ( 4 ). Reaction of these salts with [Cu(PPh 3 ) 3 Cl] afford a series of organotetrel-copper chalcogenide clusters [(CuPPh 3 ) 6 (PhTE 3 ) 2 ] with T/E = Si/S; ( 5 ), Si/Se ( 6 ),Sn/S ( 7 ) and Sn/Se ( 8 ; obtained after shorter crystallization time than 7 ). 5 - 8 share a common structural motif with two intact {PhTS 3 } units coordinating a Cu 6 moiety, which was previously reported with other ligands, and for the Sn and Ge congeners only. If the Sn/Se reaction system is allowed to crystallize more slowly, single-crystals of compound [(CuPPh 3 ) 6 (PhSnSe 3 ) 3 Cu 3 SnSe] ( 9 ) are obtained, which are based on a larger cluster structure. Hence, 9 might form from 8 through incorporation of additional cluster fragments. The experimentally and quantum chemically determined optical properties were compared to related clusters. © 2021 Wiley-VCH GmbH.
