One pseudopentasupertetrahedral chalcogenidometalate cluster, [(BuSn) 3 SnCd 4 S 13 (OH)]·6(H + DMP) (PPS-1; H + DMP = protonated 3,5-dimethylpiperidine), has been isolated by use of an organotin precursor. They are arranged to generate two types of tetrahedrally patterned cages, which further interconnect to form a diamond network. Owing to the covalent attachment of abundant alkyl groups, PPS-1 exhibits excellent hydrophobicity and could be used as an assembly substance for building liquid marbles.
