Abstract: A novel hexanuclear cage lithium complex 3 was synthesized by addition reaction of [PhN(SiMe2(OMe))Li]2 with piperidyl nitrile and its crystal structure was determined. Compound 3 was characterized by 1H NMR spectra and X-ray diffraction patterns. The crystal of compound 3 shows a cage structure and belongs to monoclinic space group: P21/n, with a=1.248 83(19) nm, b=1.402 7(2) nm, c=1.853 4(3) nm; β=95.894(2)°; V=3 229.5(8) nm3, Z=2, R1=0.047 7, GOF=0.946.
