[Li(THF)][Zn3(CH2CN)3(LiBr)(NPMe3)4] — ein funktionalisierter Phosphaniminato‐Komplex von Zink mit supramolekularer Struktur

Li(THF)]Zn₃(CH₂CN)₃(LiBr)(NPMe₃)₄] — a functionalized Phosphoraneiminato Complex of Zinc with Supramolecular Structure Li(THF)]Zn₃(CH₂CN)₃(LiBr)(NPMe₃)₄] ( 1 ) has been prepared from the heterocubane ZnBr(NPMe₃)]₄ and LiCH₂CN in tetrahydrofuran suspension to give colourless crystals which were characterized by IR‐spectroscopy and by a crystal structure analysis. 1 crystallizes in the orthorhombic space group Pnam with four units per unit cell. Lattice dimensions at 203 K: a = 2156.9(10), b = 1546.9(14), c = 1226.2(4) pm, R₁ = 0.0756. The structure consists of the anionic heterocubane Zn₃(CH₂CN)₃(LiBr)(NPMe₃)₄]^—, the eight skeleton atoms of which are the three zinc atoms and the lithium atom as well as the four nitrogen atoms of the phosphoraneiminato groups. The charge of this anionic cube is compensated by a Li⁺‐ion to which is coordinated a THF molecule, as well as three cyanomethyl‐nitrogen atoms of three different cubes. This results in the formation of a three‐dimensional supramolecular structure.
