Syntheses, structures and bioactivities of silver(I) complexes with dithioether ligands that contain a di- or triethylene glycol chain and different terminal groups
摘要:
A series of flexible dithioethyl ligands that contain ethyleneoxy segments were designed and synthesized, including bis(2-(pyridin-2-ylthio)ethyl) ether (L-1), 1,2-bis(2-(pyridin-2-ylthio) ethoxy) ethane (L-2), bis (2-(benzothiazol-2-ylthio) ethyl) ether (L-3) and 1,2-bis(2-(benzothiazol-2-ylthio) ethoxy) ethane (L-4). Reactions of these ligands with AgNO3 led to the formation of four new supramolecular coordination complexes, [Ag2L1(NO3)(2)](2) (1), [Ag2L2(NO3)(2)] (2), [AgL3(NO3)](infinity) (3) and [AgL4(NO3)] (4) in which the length of the (CH2CH2O)(n) spacers and the terminal groups of ligands cause subtle geometrical differences. Studies of the inhibitory effect to the growth of Phaeodactylum tricornutum show that all four complexes are active and the compound 4 has the highest inhibitory activity. (C) 2011 Elsevier B. V.

The reaction of bis(2-(pyridin-2-ylthio)ethyl)ether (L) with CuCl2 in CH3OH/CHCl3 solution gives a novel 24-membered ring-like coordination structure which has been characterized by elemental analysis, IR, and X-ray single-crystal diffraction. The X-ray diffraction analysis reveals that [Cu2L2Cl4] crystallizes in the triclinic, space group \(P\bar 1\). The ring-like structure is consisted of two ligands
双(2-(吡啶-2-基硫基)乙基)醚(L)与CuCl 2在CH 3 OH / CHCl 3溶液中的反应产生了一种新颖的24元环状配位结构,该结构已通过元素分析表征,红外和X射线单晶衍射。X射线衍射分析表明[Cu 2 L 2 Cl 4 ]在三斜空间\(P \ bar 1 \)中结晶。环状结构由两个配体组成,其中两个铜离子分别与两个配体的吡啶基氮原子配位。平面形双核环的最大直径约为12.7。相邻的环状单元通过CH…O氢键连接形成无限的线性链,再通过CH…Cl氢键和弱的分子间相互作用连接形成三维网络。
