First examples of racemic bis(2-dimethylaminoethylindenyl) divalent unsolvated organolanthanide complexes (Me2NCH2CH2C9H6) 2Sm (1) and (Me2NCH2CH2C9H6) 2Yb (2) have been synthesized by the reaction of (Me2NCH2CH2C9H6)K with LnI2 (Ln=Sm, Yb). The two compounds have been characterized by elemental analysis and 1H-NMR spectrometry. The X-ray crystal structure of 2 has been determined by diffraction study. The crystals are prismatic, space group P21/a (≠14), with a=17.342(6) A, b=8.542(7) A, c=17.353(2) A, β=118.70°, V=2254(1) A3, Z=4, D=1.607 g cm-3.
