[M3(L(1))3(Py)6] (where M = cobalt(II), nickel(II) and zinc(II) and L(1) is the doubly deprotonated form of a 1,4-phenylene linked bis-beta-diketone ligand of type 1,4-bis(RC(O)CH2C(O))C6H4 (R = t-Bu)) have been synthesised, adding to related, previously reported complexes of these metals with L(1) (R = Ph) and copper(ii) with L(1) (R = Me, Et, Pr, t-Bu, Ph). New lipophilic ligand derivatives with R = hexyl
不带电荷的配合物,配制成[M3(L(1))3(Py)6]型三聚金属环(其中M =钴(II),镍(II)和锌(II),L(1)是双去质子化的)已经合成了1,4-双(RC(O)CH2C(O))C6H4(R = t-Bu))类型的1,4-亚苯基连接的双-β-二酮配体报道了这些金属与L(1)(R = Ph)和铜(ii)与L(1)(R = Me,Et,Pr,t-Bu,Ph)的配合物。还制备了具有R =己基,辛基或壬基的新的亲脂性配体衍生物,用于溶剂萃取实验。H2L(1)(R = t-Bu)及其三核(三角形)镍(II)配合物[Ni3(L(1))3(Py)6] .3.5Py(R = t -Bu)也被提出。H2L(1),[Co3(L(1))3(Py)6],[Ni3(L(1))3(Py)6],[Cu3(L(1))3]的电化学研究 [Zn3(L(1))3(Py)6]和[Fe4(L(1))6](均带有R = t
