  We report the systematic synthesis and thorough characterization   of a discrete organotin sulfide cavitand,   [RB4Sn12S20]   {1, RB =   1,5-bis[(E)-2-(4-methylpentan-2-ylidene)hydrazinyl]naphthalene},   which readily undergoes a unique transformation into a stable,   rugby-ball-like capsule,   [RB3Sn6S8][(SnCl3)2]   (2), upon addition of a protic acid. DMF   molecules are embedded within the cavities of both compounds by   hydrogen-bonding interactions, spotlighting the title compounds   with respect to molecular containment.
