An organooxotin cluster [(μ-O)(μ-OMe)(L)Sn_2(CH_2Ph)_4]_2 (HL=(MeO)_2C_6H_3CO_2H) has been synthesized by the dealkylation reaction of (PhCH_2)_3SnCl with 3,4-dimethoxybenzoic acid in methanol, and was characterized by UV, IR, elemental analysis and X-ray crystal diffraction. The crystal belongs to triclinic system, space group P1 with the cell parameters: a=1.225 6(5) nm, b=1.229 4(5) nm, c=1.378 0(5) nm, α=69.784(7)°, β=68.568(7)°, γ=72.926(7)°, V=1.7801(12) nm~3, Z=1, D_c=1.549 g·cm~(-3), μ(Mo Kα)=1.447 mm~(-1), F(000)=832, R_1=0.026 1 and wR_2=0.0606. Crystal structure shows a distorted trigonal bipyramidal configuration with five-coordination for the central tin atom, and the complex has a centrosymmetric structure mode with a four-membered central endocyclic Sn_2O_2 unit. Due to the C-H…π interactions between phenyl-H and benzene ring, the adjacent molecules of the complex is linked to generate 1D ribbon structure. A theoretical investigation of one structural unit of the title complex was carried out using Gaussian 03W at LANL2DZ level. The stability and the composition of the frontier molecular orbitals confirmed the coordination geometry of the crystal structure. Thermogravimetric analysis shows that the complex is stable up to 128℃. Moreover, its fluorescence spectra was also investigated. CCDC: 841414.
摘要：
The Schiff base organotin(IV) complex {[4-Et_2NC_6H_3(O)C=NC_6H_3(O)-5-NO_2](n-Bu_2Sn)}_2 has been synthesized via the reaction between 4-(diethylamino) salicylaldehyde-2-amino-4-nitrophenol Schiff base (H_2L) and dibutyltin oxide. Complex C1 has been characterized by IR, ~1H NMR, ~(13)C NMR spectra, and elemental analysis, and its crystal structure was determined by X-ray diffraction. It crystallizes in the monoclinic system, space group P2_(1/n) with a = 15.6559(8), b = 9.1657(5), c = 18.8351(10) A, β = 107.3440(10)°, Z = 4, V = 2579.9(2) A3, D_c = 1.442 Mgm~(-3), μ(MoKa) = 1.025 mm~(-1), F(000) = 1152, R = 0.0250 and wR = 0.0633. The central Sn atom is coordinated in a hexadentate manner to assume a distorted octahedral configuration. Complex C1 was studied by TGA analysis in air atmosphere. The interaction between complex C1 and the herring sperm DNA was realized through the intercalation of the complex based on the studies by EB fluorescent probe.
摘要：
A new organotin complex [Ph3Sn(O2CC14H9)(CH3OH)]2 · CH3OH has been synthesized by the reaction of triphenyltin hydroxide with 9-anthroic acid in methanol. It was characterized by IR, 1H and 13C NMR, elemental analysis and X-ray crystal diffraction. Crystal structure shows a distorted trigonal bipyramidal configuration with five-coordination for the central tin atom. In the crystal, O-H···O hydrogen-bond interactions exist between the methanol O atom and the carbonyl O atom in an adjacent complex molecule, and between the neighboring methanol O atoms, resulting in the formation of a 1D S-shaped chain. Due to the C-H···π interactions between anthryl-H and anthracene ring, the obtained chain is further linked to form 1D ladderlike structure. Finally, a 2D network has been generated by the C-H···π interactions between methyl-H and benzene ring in the neighbouring 1D ladderlike chains. Fluorescence spectra of the complex reveals a strong emission band at 460 nm when excited with 360 nm radiation at room temperature. Thermogravimetric analysis shows that the complex is stable up to 240 °C. The stability of the complex, the orbital energies and composition characteristics of some frontier molicular orbitals have been investigaed at LANL2DZ level with G03W software.
