Dichlorohydroxo(éthyl)étain (C₂H₅SnOHCl₂.H₂O)

Abstract

C2HsSnOHCI2.H20 is monoclinic, space group C2/c, a=21.37+0.03,

Pentacoordinated molecules. 71. Hydrolysis reactions leading to ring-containing hexacoordinated distannoxanes. Tin-sulfur vs tin-oxygen bonding

“…Caled for C4H,202Cl2Sn: C, 17.05; , 4.30. Found: C,16.60; H, 3.88. Hydrogen Tetraethylammonium Dichlorobis(mercaptoethanolato)bis- 2SnCl]2[HIEt4N] (2). Tin tetrachloride pentahydrate (1.9 g, 5.4 mmol) was dissolved in acetonitrile (30 mL) and stirred.…”

“…1 crystallizes ip the monoclinic space group P2xjn with a = 6.047 (1) Á, b = 25.090 (6) A, c = 6.556 (1) A, ß = 107. 16 (1)°, and Z = 2. 2 crystallizes in the monoclinic space gruop P2\/n with a = 12.522 (2) A, b = 8.808 (1) A, c = 26.000 (2) A, ß = 104.32 (1)°, and Z = 4.…”

A discrete unsymmetrically substituted dihydrodioxadistannetane with both η1 and intramolecular η2μ2 sulfonate bondings

“…The tin-oxygen (water) distance, 2.120 Å, is rather short when compared to dialkyltetrachlorodihydrodioxadistannetane [ The monomeric molecules of 4 associated to THF are well separated in space, unlike other chloro-or sulfonatodihydrodioxadistannetanes. The last compounds form coordination polymer networks that are built through coordination bonds between sulfonate groups and tin atoms [11,13,15] or hydrogen bonds between coordinated water and/or hydroxide and ligands [2][3][4][5]10,18]. In 4, it is likely that the bulky organic ligands preclude close contacts from one molecule to another.…”

“…Then, a few examples where the tin atoms are substituted by one [2][3][4][5][6][7][8] or two [9][10][11][12][13][14][15][16][17][18] organic groups have been structurally characterized. They belong to a class of organotins that are of importance due to their structural properties as well as for their useful applications in the field of catalysis.…”

Dimeric μ-hydroxy-diphenyl(trichloroacetato)tin

“…The compound is a centrosymmetric dimer ( bridged dimers (Domingos & Sheldrick, 1974;Lecompte, Protas & Devaud, 1976;Barnes, Sampson & Weakly, 1980;Puff, Hevendehl, Hofer, Reuter & Schuh, 1985). [MezSn(OH)(NO3)]2, the only one to contain a potentially bidentate ligand in addition to the hydroxide, does not form hydrogen bonds from the ligand to the hydroxide, unlike the title compound (Domingos & Sheldrick, 1974).…”
