Herein, we present the synthesis of two pyrene‐functionalized clusters, [(R pyr Sn) 4 S 6 ]⋅2 CH 2 Cl 2 ( 4 ) and [(R pyr Sn) 4 Sn 2 S 10 ]⋅ n CH 2 Cl 2 ( n =4, 5 a ; n =2, 5 b ; R pyr =CMe 2 CH 2 C(Me)N‐NC(H)C 16 H 9 ), both of which form in reactions of the organotin sulfide cluster [(R N Sn) 4 S 6 ] ( C ; R N =CMe 2 CH 2 C(Me)N‐NH 2 ) with the well‐known fluorescent dye 1‐pyrenecarboxaldehyde ( B ). In contrast, reactions using an organotin sulfide cluster with another core structure, [(R N Sn) 3 S 4 Cl] ( A ), leads to formation of small molecular fragments, [(R pyr Cl 2 Sn) 2 S] ( 1 ), (pyren‐1‐ylmethylene)hydrazine ( 2 ), and 1,2‐bis(pyren‐1‐ylmethylene)hydrazine ( 3 ). Besides synthesis and structures of the new compounds, we report the influence of the inorganic core on the optical properties of the dye, which was analyzed exemplarily for compound 5 a via absorption and fluorescence spectroscopy. This cluster was also used for exploring the potential of such non‐volatile clusters for deposition on a metal surface under vacuum conditions.
