In the title monomeric rare earth complex, [LiNd(C(19)H(40)N(3)Si(2))(2)Cl(2)(C(4)H(8)O)(2)], the (Me(3)Si)(2)NC(NCy)(2)Nd(+) (Me is methyl, Cy is cyclo-hex-yl) and Li(THF)(2) (+) units (THF is tetra-hydro-furan) are connected by two bridging Cl atoms. The Nd(3+) ion is coordinated by two guanidinate ligands and two Cl atoms, forming a distorted chelating octa-hedral geometry. The Li(+) ion is four-coordinated by two Cl atoms and two O atoms from THF mol-ecules in a distorted tetra-hedral geometry.
在标题单体稀土配合物[LiNd(C₁₉H₄₀N₃Si₂)₂Cl₂(C₄H₈O)₂]中，[(Me₃Si)₂NC(NCy)₂]₂Nd⁺（Me为甲基，Cy为环己基）和Li(THF)₂⁺单元（THF为四氢呋喃）通过两个桥连Cl原子相连。Nd³⁺离子由两个胍基配体和两个Cl原子配位，形成扭曲的螯合八面体几何构型。Li⁺离子由两个Cl原子和来自THF分子的两个O原子以扭曲的四面体几何构型进行四配位。
