Abstract

A new method for generating La(II) complexes is described in which irradiation of single crystals of the La(III) terminal methyl complex La(SAriPr6)2CH3, AriPr6 = C6H3-2,6-(C6H2-2,4,6-iPr3)2, with Cu Kα X-rays (50 W, 8.04 keV/1.540 Å) during SCXRD experiments results in the homolytic cleavage of the La–Cmethyl bond and formation of the La(II) complex La(SAriPr6)2.
