halides containing LOMe ligand demonstrated that the assembly process produced an infinite 1D linear chain, 1D double chain and 1D ladder chain in 1, 2 and 3 respectively. Structural analysis showed that compounds 4–6 have non-polymeric structures. 4 resulted in a trimeric/monomeric motif while isostructural 5 and 6 compounds formed a discrete three coordinated mercury compound. Our results show that
在这项研究中,N-(芳基)-2-吡嗪甲酰胺配体具有两个不同的芳基(邻氨基苯甲酰基,L OMe和邻苯氧基,L OEt,基团)已被用于合成六个Hg(II)配合物,[HgCl 2(L OMe)2 ] n,1,[HgBr 2(L OMe)] n,2,[HgI 2(L OMe)] n,3,[Hg 3 Cl 6(L OEt)3 ·HgCl 2(L OEt)], 4,[HgBr 2(L OEt)], 5和[HgI 2(L OEt)], 6,以了解取代基对配合物分子结构的影响。汞的结构分析( II)含有L-卤化物OME配体展现出在组装过程中产生的无限维线性链,1D双链和1D梯子链1, 2和3分别。结构分析表明,化合物4-6具有非聚合结构。4导致三聚体/单体基序,而同构5和6化合物形成离散的三配位汞化合物。我们的结果表明,与L OMe取代基相比,L OEt基团的空间位阻显着改变了配合物的分子结构和配位范围。
