Several preparative routes to bis[N(substituted-phenyl) 4-nitro-thiobenzamidato] mercury(II) complexes are presented, including the reaction of mercury(II) oxide, fluoride, chloride, bromide, cyanide, acetate, and nitrate with N(substituted-phenyl) 4-nitro-thiobenzamide derivatives. 1 H-NMR, Raman, and IR measurements confirmed the complexation of mercury to sulphur. 相似文献

The crystal structure of the title Schiff base {systematic name: 2,2′‐[methylenedi‐p‐phenylenebis(nitrilomethylidyne)]diphenol}, C27H22N2O2, consists of intramolecularly hydrogen‐bonded molecules interlinked by C—H⋯O hydrogen bonds [C⋯O = 3.426 (2) Å and C—H⋯O = 152.7 (17)°]. The molecule is in the enol form and is located on a twofold axis. The central methane C atom of the diphenylmethane motif is displaced from the aromatic ring planes. This effect is compared with previous results, which display an inverse correlation between the out‐of‐plane displacement and the C—C—C angle around the central methane C atom. In the title compound, the displacement is 0.124 (2) Å and the C—C—C angle is 110.18 (19)°. 相似文献

The bis(calix [4] arene)3 was synthesized in moderate yield by the reaction of p-tert-butylcalix [4] arene (1) with 1,4-bis(chloromethyl) benzene (2). The conformation of all alkylated product 4 was investigated by the variable-temperature ^1H-NMR. 相似文献

The reaction of NdCl3 with 2 equiv. of Na-ButC5H4 in THF(tetrahydrofuran) gives blue crystals [(ButC5H4)2NdCl]2, C36H52Cl2Nd2 (Mr = 844.11 ), which crystallizes in the triclinic system with space group P-1. The crystal data are a= 11. 978(1), b=12. 671(4), c=12. 706(2)A, α=105.47(2), β=99. 38(1), γ=93. 15(2)°, V=1825(3)A3, Z=2, Dc=1.53g/cm3, F(000)=450, T=298K, λ(MoKα)= 0. 71069 A ,μ= 14. 97cm-1. Final R= 0. 0390, Rw,= 0. 0376 for 4329 reflections with I≥3σ(Io). The molecule has a dimer structure with two certrosymmetrical chlorine bridges. The structural trend of these analogous complexes is discussed. 相似文献
