Several compounds with unique structural motifs that have already been known from organotin sulfide chemistry, but remained unprecedented in organotin selenide chemistry so far, have been synthesized. The reaction of [(R 1 Sn) 4 Se 6 ] (R 1 =CMe 2 CH 2 C(O)Me) with N 2 H 4 ⋅H 2 O/(SiMe 3 ) 2 Se and PhN 2 H 3 /(SiMe 3 ) 2 Se led to the formation of [{(R 2 Sn) 2 SnSe 4 } 2 (μ‐Se) 2 ] ( 1 ; R 2 =CMe 2 CH 2 C(Me)NNH 2 ) and [{(R 3 Sn) 2 SnSe 4 } 2 (μ‐Se) 2 ] ( 2 ; R 3 =CMe 2 CH 2 C(Me)NNPhH)). The addition of ortho ‐phthalaldehyde to [(R 2 Sn) 4 Se 6 ] yielded a cluster with intramolecular bridging of the organic groups, namely, [(R 4 Sn 2 ) 2 Se 6 ] ( 3 ; R 4 =(CMe 2 CH 2 C(Me)NNCH) 2 C 6 H 4 ). The introduction of organic ligands with longer chains finally allowed the isolation of inorganic–organic capsules of the type [(μ‐R) 3 (Sn 3 Se 4 ) 2 ]X 2 , with R=(CMe 2 CH 2 C(Me)NNHC(O)) 2 (CH 2 ) 4 and X=[SnC 3 ], Cl ( 4 a , b ) or R=CMe 2 CH 2 C(Me)NNH) 2 and X=[SnCl 3 ] ( 5 ). The capsules enclose solvent molecules and/or anions as guests. All compounds were characterized by means of single‐crystal X‐ray diffraction studies, NMR spectroscopy, and mass spectrometry.
