Six organotin compounds with 4,4′-thiodibenzenethiol (LH2) of the type RnSnL4−nSnRn (n = 3: R = Me 1, Ph 2, PhCH23, n = 2: R = Me 4, Ph 5, PhCH26) have been synthesized. All compounds were characterized by elemental analysis, IR and NMR (1H, 13C, and 119Sn) spectra. The structures of compounds 1, 2, 4, 5 and 6 were also determined by X-ray diffraction analysis, which revealed that compounds 1 and 2 were monomeric structures, compounds 4, 5 and 6 were centrosymmetric dinuclear macrocyclic structures, and all the tin(IV) atoms are four-coordinated. Furthermore, supramolecular structures were also found in compounds 1, 2, 4, 5 and 6, which exhibit one-dimensional chains, two-dimensional networks or three-dimensional structures through intermolecular C–H?S weak hydrogen bonds (WHBs), non-bonded Sn?S interactions or C–H?π interactions. 相似文献

The triorganotin(IV) derivatives of 2-mercapto-4-quinazolinone (HSqualone) of the type, R3SnL (R = Ph 1, CH32, PhCH23, p-F-PhCH24, o-F-PhCH25, n-Bu 6), were obtained by the reaction of the R3SnCl and HSqualone with 1:1 molar ratio in benzene. All complexes 1-6 were characterized by elemental analyses, IR, 1H and 13C NMR spectroscopy and the crystal structures of complexes 1-3 were also confirmed by X-ray crystallography. The structure analyses reveal that the tin atoms of complexes 1-3 are all distorted tetrahedral geometries. Furthermore, the dimeric structures in complexes 1-3 have also been found linked by intermolecular O-H?N or N-H?O hydrogen bonding interaction. Interestingly, the dimers of complexes 2 and 3 are further linked into one-dimensional chain through intermolecular C-H?S and C-H?O weak hydrogen bonding interactions, respectively. 相似文献

A series of new organotin (IV) complexes with 3-hydroxy-2-pyridinecarboxylic acid (3-OH-2-picH) of two types: R2SnCl(3-OH-2-pic) (I) (R = Me 1, n-Bu 2, Ph 3, PhCH24) and R2 Sn(3-OH-2-pic)2 (II) (R = Me 5, n-Bu 6, Ph 7, PhCH28)have been synthesized by reactions of diorganotin (IV) dichloride with 3-hydroxy-2-pyridinecarboxylic acid in the presence of sodium ethoxide. All complexes are characterized by elemental analyses, IR spectra and NMR spectra analyses. Among them, complexes 1, 5, 6 and 7 are also characterized by X-ray crystallography diffraction analyses. Complex 1 is a 1D polymeric chain with six-coordinate tin atoms and the packing of complex 1 is stabilized by the C-H?Cl intermolecular weak interactions, thus a 2D network of 1 is formed. Complex 5 is also a 1D polymeric chain with seven-coordinate tin atoms. Complex 6 is a zigzag polymeric chain linked by Sn?O intermolecular weak interactions. Complex 7 is a monomeric complex with distorted octahedral geometry. 相似文献

Four triorganotin(IV) complexes constructed from tetrafluorophthalic acid (H2tfp) with a 1?:?1?:?1 molar ratio of H2tfp: Et3N: R3SnCl gave two of type {[R3Sn (tfp)].Et3NH}4 (R?=?Me 1, R?=?n-Bu 2), and two of type [R3Sn (tfp).Et3NH] n (R?=?PhCH2 3, Ph 4). All the complexes are characterized by elemental, IR, 1H, 13C and 119Sn NMR analyses. Complexes 1 and 4 were also confirmed by X-ray crystallography. Complex 1 is tetranuclear with a 28-membered C16O8Sn4 macrocyclic ring system with a cavity. The supramolecular structure of 1 has been found to consist of a three-dimensional network built up by intermolecular N–H?···?O, C–H?···?O hydrogen bonds and C–F?···?F weak interactions. Complex 4 is an infinite polymeric structure. The salient feature of the supramolecular structure of 4 is that of a two-dimensional plane, in which intermolecular N–H?···?O and C–H?···?π hydrogen bonds are important. 相似文献

Eight diorganotin(IV)-oxo-carboxylates {[R2Sn(O(O)CR′)]2O}2?·?Y (R′?=?C4H3N2Y?= H2OR?=?nBu 1, Y?=?0 R?=?Me 2, Y?=?0 R?=?C6H5 3, Y?=?0 R?=?C6H5CH2 4; R′?=?CH2SC4H3N2-2,6Y?=?0 R?=?nBu 5, Y?=?CH2Cl2R?=?Me 6, Y?=?0 R?=?C6H5 7, Y?=?0 R?= C6H5CH2 8) have been prepared in 1?:?1 molar ratios by reactions of diorganotin(IV) oxide with 2-pyrazinecarboxylic acid or (2-pyrimidylthio)acetic acid, respectively. All the complexes are characterized by elemental analysis, IR, 1H NMR and 13C NMR spectra. Except for 2, 4 and 7, the complexes are also characterized by X-ray crystallography diffraction analyses, which reveal that the complexes adopt the familiar dicarboxylato tetraorganodistannoxane structural mode. Among them, the evident difference is that weak intramolecular interactions between Sn and N atoms are recognized in complexes 1 and 3. However, for complex 5 two different coordination modes are found in the same lattice. 相似文献

All the complexes were characterized by elemental analysis, TGA, IR and NMR (1H, 13C, 119Sn) spectroscopy analyses. Among them, except for complexes 5 and 6, all complexes were also characterized by X-ray crystallography diffraction analysis. Crystal structures show that complexes 1-10 adopt 1D infinite chain structures which are generated by the bidentate O, O or N, O and the five-coordinated tin centers. Significant O-H?O, and N-H?O intermolecular hydrogen bonds stabilize these structures. Complex 11 is a 42-membered macrocycle containing six tin atoms, and forms a 2D network by intermolecular N-H?O hydrogen. 相似文献

Six new organotin carboxylates based on 1,3-benzenedicarboxylic acid and 1,4-benzenedicarboxylic acid derivatives, namely (Ph3Sn)2(2,5-L1)(C2H5OH)2 (1) (2,5-H2L1 = 2,5-dibenzoylterephthalic acid), (Ph3Sn)2(2,5-L2)(C2H5OH)2 (2) (2,5-H2L2 = 2,5-bis(4-methylbenzoyl)terephthalic acid), (Ph3Sn)2(2,5-L3)(C2H5OH)2 (3) (2,5-H2L3 = 2,5-bis(4-ethylbenzoyl)terephthalic acid), [(n-Bu2Sn)4(4,6-L1)O2(OH)(OC2H5)]2·2(C2H5OH) (4) (4,6- H2L1 = 4,6-dibenzoylisophthalic acid), [(n-Bu2Sn)4(4,6-L1)O2(OH)(OC4H9)]2·2(C4H9OH) (5) and [(n-Bu2Sn)4(4,6-L2)O2(OH)(OC2H5)]2·2(C2H5OH) (6) (4,6-H2L2 = 4,6-bis(4-methylbenzoyl)isophthalic acid), have been synthesized. All the organotin carboxylates have been characterized by elemental analysis, IR, 1H and 13C NMR spectroscopy and X-ray crystallography diffraction analyses. The structural analysis reveals that complexes 1-3 show similar structures, containing binuclear triorganotin skeletons. The significant intermolecular O-H?O hydrogen bonds linked the complexes 1-3 to form a novel 2D network polymer with 38-member macrocycles. In complexes 4-6, two Sn4O4 ladders are connected by two 1,3-benzenedicarboxylic acid derivatives to yield ladder-like octanuclear architectures and form macrocycle with 24 atoms. In addition, the antitumor activities of complexes 1-6 have been studied. 相似文献

Two types of diorganotin(IV) complexes {[R2Sn(O2CC4H3N2)]2O}2 (R = n-octyl 1, 2-ClC6H4CH23, 2-FC6H4CH25, 4-FC6H4CH27) and R2Sn(O2CC4H3N2)2 (R = n-octyl 2, 2-ClC6H4CH24, 2-FC6H4CH26, 4-FC6H4CH28) were prepared by reactions of diorganotin oxide with 2-pyrazinecarboxylic acid. The complexes 1-8 are characterized by elemental analysis, IR and NMR (1H, 13C, 119Sn) spectroscopies. The complexes {[(n-C8H17)2Sn(O2CC4H3N2)]2O}2 (1) and (n-C8H17)2Sn(O2CC4H3N2)2 (2) are also determined by X-ray single crystal diffraction, which reveal that the endo-cyclic tin atom of complex 1, is seven-coordinate, and the exo-cyclic tin atom is hexa-coordinated geometry, while the complex 2 is seven-coordinated geometry.

Triorganotin(IV) hydrides and cyclopentadienides as well as hexaorganodistannanes containing the moiety LCN (2-(N,N-dimethylaminomethyl)phenyl-) as chelating ligand and phenyl, n-butyl or t-butyl substituents were prepared and characterized by NMR and XRD. The compounds reveal trigonal bipyramidal geometry around the central tin atom except for the distannanes in which the tin atom has tetrahedral configuration. The di-n-butyl distannane cannot be oxidized by oxygen or heavier chalcogens and give no tin radical when irradiated by UV light or treated with the TEMPO - free radical at room temperature. LCN(t-Bu)2SnH undergoes reaction in solution toward the corresponding distannane. The hydrostannation reaction of LCN(n-Bu)2SnH with ferrocenylacetylene was investigated. The CO2 activation by LCN(n-Bu)2SnH was also examined. 相似文献

Seven new triorganotin(IV) complexes of the type R3SnL (L=N-phthaloyl derivatives of glycine, DL-alanine or N-acetyl- and N-benzoyl-glycine and -cysteine; R-n-C4H9 or C6H5) have been prepared by reacting the sodium salt of the ligand and the triorganotin(IV) chloride in 1:1 molar ratio in methanol. The complexes have been characterized by elemental analysis, molecular mass determination, IR and 1H NMR spectroscopy. The complexes are monomeric in molten camphor and are moderateely soluble in the common organic solvents. The spectral data support cis five-coordinate complexes with an unsymmetrical bidentate coordination of the carboxylate group to tin. The complexes exhibit some insecticidal effect on Bean Weevils (Sitophilus granaria) even at low concentration and they also show fungicidal activity on Aspergillus niger and Helminthosporium taulosum. Some of the complexes are found to be more effective than tri-n-butyltin and triphenyltin chlorides. 相似文献

AbstractThe N(4)-methylthiosemicarbazone derivatives H2DDMT (1) and H2DMMT (2) have been prepared from the reaction of 4-methylthiosemicarbazide with 2,3-dihydroxybenzaldehyde and 2-hydroxy-5-methylbenzaldehyde, respectively. Six new organotin(IV) complexes, [MeSnCl(DDMT)] (3), [BuSnCl(DDMT)] (4), [PhSnCl(DDMT)] (5), [MeSnCl(DMMT)] (6), [BuSnCl(DMMT)] (7), and [PhSnCl(DMMT)] (8) have been synthesized by direct reaction of corresponding organotin(IV) chloride(s) with these ligands. The ligands and their compounds have been characterized by elemental analysis, molar conductivity, UV–Vis, FT-IR, and NMR (1H, 13C, and 119Sn) spectroscopy. The molecular structures of 1 and 2 were determined by X-ray crystallography. Spectroscopic data suggested that the ligands were coordinated to tin(IV) as dinegative tridentate via phenoxide-O, azomethine-N, and thiolate-S atoms. The crystal structures revealed that the ligands exist in thione form in the solid state. In vitro cytotoxicity assays were carried out for all the compounds against MCF-7 cancer cell line. The results have shown that different organotin(IV) groups showed characteristic differences in their biological activity. 相似文献
