Y. Chauvin et al., SYNTHESIS AND STRUCTURAL DETERMINATION OF A NEODYMIUM(III) COMPLEX DERIVED FROM OPENTADIENYL-1-METHYLETHYL)-9,10-DIHYDROANTHRACENE, Journal of organometallic chemistry, 455(1-2), 1993, pp. 89-92
Neodymium trichloride reacts with 2 equiv. of the lithium salt of open
tadienyl-1-methylethyl)-9,10-dihydroanthracene in THF to give the ''at
e'' complex [Li(THF)4][Nd{(C5H4)CMe2(C14H10)}2] which has been charact
erized by its crystal structure and elemental analysis. The neodymium
atom is situated in tetrahedral environment. It is eta5-bonded to the
two cyclopentadienyl rings and sigma-bonded to the C(10) atoms of the
two dihydroanthracene moieties.
