Xg. Zhou et al., SYNTHESIS AND STRUCTURE OF A NEW ORGANOLANTHANIDE OXIDE COMPLEX, 3C5H4)(3)YB-4(MU-CL)(6)(MU(3)-CL)(MU(4)-O)(THF)(3), Journal of organometallic chemistry, 503(1), 1995, pp. 11-13
Reaction of NaCp'(Cp' = C5H4CH3) with YbCl3 and YbOCl in THF results i
n the formation of a new complex, Cp(3)'Yb-4(mu-Cl)(6)(mu(3)-Cl)(mu(4)
-O)(THF)(3) (1). The X-ray crystal structure of 1 reveals an oxygen-ce
ntred tetrahedral arrangement of ytterbium atoms which has mu-Cl group
s bridging each edge and a mu(3)-Cl ligand over the trianglar face com
posed of Yb atoms with Cp' groups.
