夹心金属阳离子和[M(mnt)_2]阴离子所成盐的合成、结构及固体物理性质

Synthesis, Structure and Solid State Physical Properties of the Salts Consisted of the Sandwich Cations and [M (mnt)_2] Anions

本工作设计和合成了十个由夹心型金属有机化合物阳离子与金属二硫醇配合物[M(mnt)_2]阴离子组成的金属有机盐类化合物:(M'Cp_2)[M(mnt)_2]或[FeCp(Tol)]_n[M(mnt)_2],其中M=Ni,Pd,Co,Cu或Zn;M’=Fe或Co;Gp代表环戊二烯基;Tol代表甲苯;mnt代表;n=1或2).通过元素分析、IR和NMR对化合物进行表征,测定了[FeCp(Tol)]_2[Ni(mnt)_2]的单晶结构.Mossbauer谱和ESR表明(FeCp_2)[Ni(mnt)_2]是个混合价化合物,提出了该化合物的生成反应机理.测定了所有化合物的固体电导率和部分化合物的固体磁学性质.

Two series of the organometallic salts, (M'Cp_2)[M(mnt)_2] and [FeCp(Tol)]_n [M(mnt)_2] (M = Ni, Pd, Co, Cu or Zn; M' = Fe or Co; Cp = cyclopentadienyl; Tol = Toluene; mnt = maleonitriledithiolate; n=1 or 2), were synthesized. Their structure was confirmed by elemental analysis, IR and NMR. The single crystal structure of [FeCp(Tol)]_2[Ni(mnt)_2] was determined by X-ray diffraction. Mossbauer and ESR spectra indecated that (PeCp_2) [Ni(mnt)_2] was a mixed valence compound and the mechanism of its formation reaction was proposed. The solid state conductivity of all the compounds and the magnetic property of some compounds were measured.
