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 [(R1Sn)4Se6] (R1=CMe2CH2C(O)Me) with N2H4⋅H2O/(SiMe3)2Se and PhN2H3/(SiMe3)2Se led to the formation of [(R2Sn)2SnSe4}2(μ‐Se)2] (1; R2=CMe2CH2C(Me)NNH2) and [(R3Sn)2SnSe4}2(μ‐Se)2] (2;

Directed Formation of an Organotin Sulfide Cavitand and Its Transformation into a Rugby-Ball-like Capsule
We report the systematic synthesis and thorough characterization of a discrete organotin sulfide cavitand, [R(B)(4)Sn(12)S(20)] 1, R(B) = 1,5-bis[(E)-2-(4-methylpentan-2-ylidene)hydrazinyl]naphthalene}, which readily undergoes a unique transformation into a stable, rugby-ball-like capsule, [R(B)(3)Sn(6)S(8)][(SnCl(3))(2)] (2), upon addition of a protic acid. DMF molecules are embedded within the cavities
