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：
The asymmetric unit of the title compound, C6H9N3, contains three crystallographically independent molecules of similar geometry. All of the molecules are almost planar, with r.m.s. deviations of 0.003, 0.016 and 0.005 14;Å. In the crystal, the molecules are linked by N - HN hydrogen bonds into zigzag ribbons parallel to the c axis, generating rings of R 2 2(8) graph-set motif.
摘要：
The tris[（2-methyl-2-phenyl）propyl]（2,4-dinitro-phenolato）tin was synthesized by the reaction of bis[tri（2-methyl-2-phenyl）propyltin] oxide with 2,4-dinitrophenol. The compound was characterized by IR, 1H NMR spectra and elemental analysis. The crystal structure has been determined by X-ray diffraction. The crystal belongs to the monoclinic system, space group P21/n with a = 0.9649（0）, b = 1.0087（8）, c = 3.4867（4） nm, β = 90.965（7） , Z = 4, V = 3.3933（7） nm3, Dc = 1.369 Mg·m-3, （MoKa） = 0.796 mm-1, F（000） = 1440, R = 0.0345 and wR = 0.0821. The tin atom has a distorted tetrahedral geometry. The 2D network structure of the complex is formed by hydrogen bonds and π-π effects. The stabilities, orbital energies and composition characteristics of some frontier molecular orbitals of the complexes have been investigated with the aid of G98W software.
