As part of an effort to develop the coordination environments of the lanthanides using phosphido ligands, as well as to investigate the corresponding bonding aspects, the authors have been examining the reaction behavior of lanthanide triflates with lithium bis(tert-butyl) phosphide. Recently, the authors described the synthesis and structural characterization of a novel four-coordinate homoleptic phosphido complex of divalent ytterbium: Yb[({mu}-P{sup t}Bu{sub 2}){sub 2}Li(thf)]{sub 2}. A question of considerable interest is how the size of the lanthanide cation influences the observed structure. To probe this issue, the authors decided to determine whether the structure of the above-mentioned ytterbium species in the solid state would change employing the larger samarium(II) cation in place of ytterbium-(II). Additionally, Yb[({mu}-P{sup t}Bu{sub 2}){sub 2}Li(thf)]{sub 2} was found to exhibit strongly photoluminescent properties. The authors wanted to find out whether this behavior is determined by the ligand system or the metal center. Here, the authors report the synthesis and X-ray crystal structure determination of a tetrakis(phosphido) species of divalent samarium.
