Formation and crystal structure of FcCH(t-Bu)NHCH(Me)CH2OMe center dot LiIcenter dot Et2O

The title compound FcCH(t-Bu)NHCH(Me)-CH2OMe . LiI . Et2O (1 . LiI . Et2O) was obtained by reaction of FcCH(t-Bu)N(Li)CH(Me)CH2OMe with MeI in a molar ratio 1: 1 in diethylether. The Li atom is substituted by an H atom yieldi ng the secondary amine. The formation oi the expected N-methyl substituted species could not be observed. 1 creates monomeric molecules with four coor dinate Li atoms as a result of Li-N and Li-O interactions of the correspond ing atoms of the ferrocenyl ligand and a solvent molecule. 1 . LiI . Et2O: Space group P2(1)2(1)2(1), Z = 4, lattice dimensions at -60 degreesC: a = 1 0.492(2), b = 13.225(2), c = 18.846(3) Angstrom, beta = 90 degrees, R-1 = 0 .0478, wR(2) = 0.0801
