Wj. Evans et al., SAMARIUM(II) SURROUNDED BY ONLY OXYGEN DONOR LIGANDS - [KSM(MU-OC(6)H(2)BU(2)(T)-2,6-ME-4)(3)(THF)](N), Inorganic chemistry, 34(1), 1995, pp. 5-6
Although oxygen donor ligands are common in lanthanide chemistry and S
m(II) complexes are being extensively investigated, no crystallographi
cally characterized Sm(II) complexes containing only oxygen donor liga
nds have been previously reported. The first example shown here has be
en isolated as a potassium ''ate'' complex which has an extended struc
ture due to potassium arene and aryloxide bridging.
