Amino Acid Functionalized Organotin Trichlorides and Their Tin Sulfide Clusters

“…In contrast to the synthesis of the related keto functionalized compound [(R 1 Sn) 4 S 6 ], which precipitates after a few minutes from the reaction solution, [23] the clusters equipped with R AAc ligands do not precipitate at all. The chemical shifts of the signals are almost identical with those observed for the defect-heterocubane-type clusters (9)(10)(11)(12)(13)(14)(15)(16). The products were re-dissolved in DCM to separate them from sodium chloride, which precipitates during the reaction with Na 2 S. Mass spectra of these solutions informed about the chemical composition of the products.…”

“…[4,5] Such clusters have been isolated in many different inorganic core architectures, with the most dominant ones possessing a defect-heterocubane-type [(RSn) 3 S 4 Cl], a "doppeldecker"-type [(RSn) 4 S 6 ], and the isomeric adamantane-type structure [(RSn) 4 S 6 ], respectively. [5][6][7][8][9][10][11][12][13] Metal chalcogenide clusters furthermore play an important role for bio-relevant developments. [14] Here, tin sulfide clusters can be potentially useful as cytotoxic agents, as they decompose under slightly acidic conditions to release cytotoxic H 2 S. [15] This may allow for a targeted delivery of H 2 S to undesirable cells, the environment of which can be more acidic than that of healthy cells.…”

“…Chalcogenidometallate clusters provide a perspective into a wide field of applications, Some organotetrel chalcogenide clusters that combine tetrel atoms Si, Ge, or Sn and chalcogen atoms S, Se, or Te with different organic substituents R, for instance, show extreme nonlinear optical properties , . Such clusters have been isolated in many different inorganic core architectures, with the most dominant ones possessing a defect‐heterocubane‐type [(RSn) 3 S 4 Cl], a “doppeldecker”‐type [(RSn) 4 S 6 ], and the isomeric adamantane‐type structure [(RSn) 4 S 6 ], respectively …”

Current advances in tin cluster chemistry

“…Without going too much into details of synthesis procedures that can be found elsewhere, [12][13][14][15][16][17] structural, chemical, and physical properties of the selected examples of tin clusters will be named, illustrating the breadth and beauty of this area of research, and also pointing to possible implications of this eld for inorganic, organoelement, and materials chemistry.…”

A Methylated Oxo‐Thio Stannate Cluster from a Non‐Innocent Ionic Liquid

“…The investigation of nano-sized metal chalcogenide compounds is a very topical field of inorganic and materials chemistry, [1][2][3][4] owing to corresponding properties that range from uncommon structural [5][6][7][8] and opto-electronic [9][10][11][12] properties to specific reactivities. [13,14] Of particular interest with regard to ecological and economical aspects are mild preparation conditions and controlled post-synthetic treatment.…”
