Abstract

A series of metal-centered ferrocene compounds has been designed by using 5-ferrocenylpyrimidine (L1) and ferrocenylpyrazine (L2). These ligands, when combined with transition metal salts, produce mixed-metal polynuclear complexes with structural diversity. Reaction of L1 with M(SCN)(2) (M = Ni, Co) produces the pinwheel-like 4:1 complexes (L1)(4).M(SCN)(2), while reactions of L1 and L2 with Cu(NO(3))(2) give the 3:1 complex (L1)(3).Cu(NO(3))(2) and the 2:1 complex (L2)(2).Cu(NO(3))(2), respectively. Reactions of L1 and L2 with M(hfac)(2) (hfac = 1,1,1,5,5,5-hexafluoroacetylacetonate, M = Mn, Ni, Cu, Zn) produce 2:1 complexes (L)(2).M(hfac)(2) with cis and trans configurations, respectively. Crystal structures as well as solid-state electrochemical properties of these redox active complexes were investigated.

摘要

通过使用5-二茂铁基嘧啶（L1）和二茂铁基吡嗪（L2）设计了一系列以金属为中心的二茂铁化合物。这些配体与过渡金属盐结合时，会产生具有结构多样性的混合金属多核配合物。L1与M(SCN)₂（M = Ni、Co）反应生成风车状的4:1配合物(L1)₄·M(SCN)₂，而L1和L2与Cu(NO₃)₂反应分别生成3:1配合物(L1)₃·Cu(NO₃)₂和2:1配合物(L2)₂·Cu(NO₃)₂。L1和L2与M(hfac)₂（hfac = 1,1,1,5,5,5-六氟乙酰丙酮，M = Mn、Ni、Cu、Zn）反应分别生成具有顺式和反式构型的2:1配合物(L)₂·M(hfac)₂。研究了这些氧化还原活性配合物的晶体结构以及固态电化学性质。
