Crystal structure of (N-o-tolylpyridine-2-carbaldimine)triclorovinyltin(rV), C15H15Cl3N2Sn

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.…”

Synthesis, characterization and crystal structures of polymeric and dimeric triphenyltin(IV) complexes of 4-[((E)-1-{2-hydroxy-5-[(E)-2-(2-carboxyphenyl)-1-diazenyl]phenyl}methylidene)amino]aryls

“…06.030 tin(IV). In search of organic ligands/complexes having mesogenic behaviour, we have recently synthesized a number of 4-[((E)-1-{2-hydroxy-5-[(E)-2-(2-carboxyphenyl)-1-diazenyl]phenyl}methylidene)amino]aryl ligands and efforts have also been made to characterize these ligands by single crystal X-ray crystallographic techniques, for example, L 1 HH 0 [this work], L 2 HH 0 [7] and L 3 HH 0 [1]. However, this family of ligands and its organotin(IV) derivatives await characterization as mesogens and the determination of other essential features such as thermotropic, lyotropic and macroscopic (e.g., optical) properties.…”

“…In view of the possible importance of these ligands and as a continuation of our studies of biological organotin compounds [12,13,15,16] and the structural chemistry of these complexes [12,13,[15][16][17][18][19][20][21][22][23][24][25][26][27][28][29], we now report the synthesis and spectroscopic characterization of Ph 3 SnLH complexes (where LH is the deprotonated ligand derived from 4-[((E)-1-{2-hydroxy-5-[(E)-2-(2-carboxyphenyl)-1-diazenyl]phenyl}methylidene)amino]aryls) (L 1-4 HH 0 , Fig. 1).…”

Synthesis and characterization of triphenyltin(IV) 5-[(E)-2-(aryl)-1-diazenyl]-2-hydroxybenzoates. Crystal and molecular structures of Ph3Sn{O2CC6H3-p-OH[NN(C6H4-4-CH3)]} and the 2,2′-bipyridine adduct Ph3Sn{O2CC6H3-p-OH[NN(C6H4-2-CH3)]}OH2·C10H8N2

“…10.008 trans-trigonal bipyramidal (II) [1,2], cyclotetrameric, distorted trans-trigonal bipyramidal (III) [8], and cyclohexameric (IV, similar to II) [9] geometries have been noted. Recently, we have reported a series of triorganotin carboxylates involving azo-organic residues and their crystal structures fall within the boundaries of the motifs specified above [10][11][12][13]. In these systems, triphenyltin azocarboxylates invariably display distorted tetrahedral coordination at the Sn atom (motif Ia).…”
