Organotin–Oxido Cluster‐Based Multiferrocenyl Complexes Obtained by Hydrolysis of Ferrocenyl‐Functionalized Organotin Chlorides

“…[8] The hydrolysis of organotin halides to form tin oxido compounds without ferrocenyl units has been investigated for many years. Clusters with different shapes, including four-and six-membered rings, [9] adamantanes, [10] or mono-, double-, and triple-ladders, [10,11] were reported, and also more complicated compounds with up to twelve tin atoms, such as in [(iPr-Sn) 9 (OH) 6 O 8 Cl 5 ], [12] {[(iPrSn) 12 (O) 14 (OH) 6 ]Cl 2 }, [13] or {[(nBu-Sn) 12 (O) 14 (OH) 6 ][OH] 2 }, [14] were obtained by hydrolysis of the monoorganotin compounds. For some of the compounds, the formation mechanisms have been investigated.…”

Synthesis and structural characterization of monomeric and polymeric supramolecular organotin(IV) 4-chlorophenylethanoates

“…A large number of supramolecular organotin(IV) carboxylates have been prepared and structurally characterized [1,2]. Structural types such as monomers, dimers, tetramers, oligomers, and polymers have been reported [3][4][5][6][7]. The diverse structural motifs found in this family of complexes have been attributed to the nature of carboxylic acid, tin-bound R groups, and metal-ligand molar ratio [8,9].…”
