The reaction of [( R 1 Sn) 3 Se 4 Cl] ( R 1 = CMe 2 CH 2 COMe) with [Pd(PPh 3 ) 2 Cl 2 ], (SiMe 3 ) 2 Se, and hydrazine hydrate yields a new Pd/Se cluster, [Pd 3 (PPh 3 ) 5 (SeH)(μ 3 ‐Se) 2 ][SnCl 3 ] ( 1 ). Using [( R 1 Sn) 4 Se 6 ] as reactant and varying the reaction conditions as well as the addition of (SiMe 3 ) 2 Se and hydrazine hydrate, [Pd 3 (PPh 3 ) 5 (SnCl 3 )(μ 3 ‐Se) 2 ][SnCl 3 ] ( 2 ) and [Pd 2 (PPh 3 ) 3 Cl{Sn R 2 Cl 2 }(μ 3 ‐Se) 2 ] ( 3 ) can be isolated. 3 is the first compound based on a [Pd 2 SnSe 2 ] moiety, which furthermore exhibits a functional organic group at the tin atom. Its photoluminescence and absorption spectra are discussed as well. All compounds were characterized by single‐crystal X‐ray diffraction, indicating a bipyramidal structure. Mass spectrometric analyses of the reaction solutions provide some insight into the formation of the clusters.
