The crystal structure of the title complex[Li (dme)3] [(t-BuC_5H_4)_2Gd (NPh_2)_2]·1/2dme,C56H81O7N2LiGd(M,r=1058. 63), has been determined by single-crystal X-ray diffraction. The crystal is triclinic with space group P1, a=12. 741 (3),b =13. 353(3), c=16. 843(4) A, a=94. 70(2), β=91. 57(2)’, r=92. 03(2), V=2852. 7(1) A3, Dc= 1.23g/cm3, F(000)=1038, u=12. 5 cm-1, Z=2, and finalR=0. 050 and Rw=0. 045 for 5829 reflections (I≥3d(I)). The structure analysis re-vealed that the complex consists of disconnected ion pairs of (Li (dine)3 ]+ and [(t-BuC5H4),Gd (NPh2)2]-. The Gd atom is connected to two n5-bonded t-butylcy-clopentadienyl groups and two a bonded diphenylamidos in a distorted tetrahedral ar-rangement. The Li atom is coordinated by six O atoms from three dimethoxyethane lig-ands forming an octahedron structure.
