摘要：
The triphenyltin complex with salicylidene-2-aminophenol (C_(31)H_(24)NO_2Sn, 1) has been synthesized and characterized by elemental analysis, IR spectroscopy, thermogravimetric analysis, and X-ray single-crystal diffraction. The complex crystallizes in monoclinic system, P2_1/c space group with a = 1.09515(8), b = 1.17739(8), c = 2.29075(14) nm, β = 117.070(4)°, V = 2.6302(3) nm~3, Z = 4, D_c = 1.417 g/cm~3, μ = 0.999 mm~(-1), F(000) = 1123, R = 0.0472 and wR = 0.1169. X-ray single-crystal diffraction showed that 1 demonstrates a one-dimensional chain structure. The quantum chemical calculation of 1 has been investigated. Complex 1 emits fluorescence at 558 nm and exhibits certain inhibitory activity against NCI-H460, A549 and MCF-7.
摘要：
A novel anionic organotin(IV) complex I {[p-ClC6H4CH2)Sn(H2O)(Cl)(2)OCOCH(O)CH(O)CO2Sn(H2O)(Cl)(2)(p-ClC6H4CH2)]center dot 2(HNEt3)} (1) was synthesized by the reaction of di(p-chlorobenzy)tin dichloride with the D-tartaric acid in 2:1 molar in the presence of an organic base triethylamine. The structure was characterized by elemental analysis, IR, TG, XRD and single-crystal X-ray diffraction. It crystallizes in triclinic, P-(1) over bar space group, with a = 0.7067(1), b = 1.9762(3), c = 2.2383(3) nm, alpha = 91.544(2)degrees, beta = 90.075(2)degrees, gamma = 90.110(2)degrees, V = 3.1247(7) nm(3), Z = 3, D-c = 1.621 g/cm(3), mu(MoK alpha) = 16.29 cm(-1), F(000) = 1530, R = 0.0394, wR = 0.1092, (Delta rho)(max) = 1224 and (Delta rho)(min) = -840 e/nm(3). The stabilities, orbital energies and composition characteristics of some frontier molecular orbitals of 1 have been carefully investigated with quantum chemistry calculation. In addition, the in vitro antitumor activity suggested that 1 had stronger inhibitory activity on H460, MCF7 than on A549.
摘要：
Finding a new derivative structure of FeSe-based superconductors with a high superconducting transition temperature ( Tc) is of great significance. Here, in this work, an organic-ion-[cetyltrimethyl ammonium ( CTA+)]-intercalated FeSe-based superconductor (CTA)0.3FeSe with Tc as high as 45 K is synthesized by an electrochemical intercalation method. The as-prepared (CTA)0.3FeSe has a hybrid crystal structure consisting of double layers of CTA+ and one layer of FeSe, which is consistent with a lateral-bilayer model. The superconductivity of (CTA)0.3FeSe is confirmed by magnetic susceptibility. Furthermore, a negative pressure effect on superconductivity dTc/dP=−5 K/GPa is observed. This is the first pure organic-ion-intercalated FeSe-based superconductor with a high Tc and high crystallinity. Our work offers a new method to modify the interface interaction between the FeSe layer and the intercalator, and sheds new light on finding new FeSe-based superconductors with higher Tc.

摘要：
A room-temperature and PTC-free copper-catalyzed N-arylation of aliphatic amines in neat water has been developed. Using a combination of CuI and 6,7-dihydroquinolin-8(5H)-one oxime as the catalyst and KOH as the base, a wide range of aliphatic amines are arylated with various aryl and heteroaryl halides to give the corresponding products in up to 95% yield.
摘要：
Diruthenium ethynyl complexes 1-3 (1: 1,5-dithia-s-indacene-4,8-dione; 2: 4,8-diethoxybenzo[ 1,2-b:4,5-b']dithiophene; 3: 4,8-didodecyloxybenzo[ 1,2-b:4,5-b']dithiophene) have been synthesized by incorporating the respective conjugated heterocyclic spacer and characterized by NMR and elemental analysis.The effects of bridge ligands' properties on electronic coupling between redox-active ruthenium terminal groups were investigated by electrochemistry,UV/vis/near-IR and IR spectroelectrochemistry combined with density functional theory (DFT) and time-dependent DFT calculations.Electrochemistry results indicated that complexes 1-3 exhibit two fully reversible oxidation waves,and complexes 2 and 3 with electron-rich and π-conjuagted bridge ligands are characterized by excellent electrochemical properties.Furthermore,the larger v(C≡C) separation from the IR spectroelec-trochemical results of 2 and 3 and the intense NIR absorption features of singly oxidized species ~(2+) and ~(3+) revealed that their molecular skeletons have superior abilities to delocalize the positive charge.The spin density distribution from DFT calculations proved the conclusions of this study.
