Materials Chemistry and Structural Chemistry of Tin Compounds

Abstract

Key indicators: single-crystal X-ray study; T = 130 K; mean (C-C) = 0.003 A ˚ ; R factor = 0.020; wR factor = 0.047; data-to-parameter ratio = 20.7. In the title compound, [Sn(C 2 H 2 O 2 S) 2 (C 2 H 6 OS) 2 ], the mercaptoacetato ligands chelate to Sn IV through S and one O atoms. The metal centre is also coordinated by two dimethyl sulfoxide (DMSO) ligands through the O atom, leading to an overall distorted octahedral coordination environment for the Sn IV atom. The molecular adduct lies on a twofold rotation axis.

Organotin(IV) complexes with 2-acetylpyridine benzoyl hydrazones: antimicrobial activity

“…17 It has also been shown that metal complexes with hydrazones can be potent inhibitors of cell growth and DNA syntheses. 18 Tin compounds present applications as PVC stabilizers, 19 for chemical vapor decomposition (CVD), 20 in non-linear optics 21 and in catalyses. 22 Organotin complexes present innumerous pharmacological applications as antitumorals, 23 antimicrobials 24,25 and biocides.…”

Synthesis, characterization and thermodynamic studies of complexes of dimethyl, diethyl, and diphenyltin(IV) dichlorides with (2H)-1,4-benzothiazine-2,3-(4H)-dione dioxime

“…Organotin(IV) complexes have a wide range of applications such as PVC stabilizers [1], for chemical vapor decomposition (CVD) [2], in non-linear optics [3] and in catalyses [4][5][6]. Organotin complexes present innumerous pharmacological applications as antitumorals [7], antimicrobials [8,9] and biocides [10] and locking agent in the formation of dinuclear complexes [11].…”
