The Mössbauer recoil-free fraction and structure. Part 3. Triorganotin arylazobenzoates

Molecular basis of the interaction of novel tributyltin(IV) 2/4-[(E)-2-(aryl)-1-diazenyl]benzoates endowed with an improved cytotoxic profile: Synthesis, structure, biological efficacy and QSAR studies

“…1, with selected geometric parameters collected in Table 1). Similar tetrahedral geometry about the Sn atom was observed in (Ph 3 Sn[O 2 CC 6 H 4 (N = NC 6 H 3 -2-OH-5-Me)-o]) and its acetone solvated complex [46,47] [42]. The other carboxylate O atom of the benzoate ligand also coordinates weakly to the Sn atom with the Sn (1)⋯O(2) distance being 2.982(2) Å.…”

Syntheses and characterization of triorganotin complexes: X-ray crystallographic study of triorganotin pyridinedicarboxylates with trinuclear, 1D polymeric chain and 2D network structures

“…Among them, the study of the structural chemistry of triorganotin carboxylates has received considerable attention owing to the various structural types that may be adopted in the solid state [12][13][14][15][16][17][18][19]. Although a large number of structural studies have been carried out on the triorganostannyl esters of monofunctional carboxylic acids [20], relatively little work has so far been undertaken on the triorganotin esters of dicarboxylic acids [21][22][23][24].…”

The synthesis and structural characterization of a series of triphenyltin(IV) esters of N-arylidene-ω-amino acids

“…X-ray structural analyses for Ph,SnOCOR where R contains a phenolic functional group as in Ph,SnOCOC6H4-OH-o (6), Ph3SnOCOC6H40CH3-o (6), Ph3SnOCOC6H4-OPh-o (7), Ph3SnOCOC6H4(N2C6H3MeOH) (the ligand in this complex is o-(2-hydroxy-5-methy1phenylazo)-benzoate (8) failed to firmly establish the presence of an linkage even though such a network was reported for the trimethyltin(1V) analogue, Me,SnOCOC6H40H-o (9). W e describe here the synthesis and characterization by IR and NMR spectroscopic techniques of a series of triphenyltin derivatives of N-salicylidene-o-amino acids, 2-HOC6H4-CH=N(CH,),,COOH, and N-2-hydroxynaphthylidene-oamino acids, 2-HOC,,H6CH=N(CH2),,COOH (n = 1, 2, 3, and 5).…”
