The reaction of in-situ prepared Li2[OPO] with SnCl4 in THF at −35 °C produced [OPO]SnCl2(THF) as a THF adduct. Addition of SnCl4 to a THF solution of H2[OPO] in the presence of 2 equiv of NEt3 at room temperature led to the formation of the “ate” complex {[OPO]SnCl3}(HNEt3). The metathetical reactions of Li2[OPO] with R2SnCl2 (R = Me, n-Bu) in THF at −35 °C generated the corresponding five-coordinate dialkyl complexes [OPO]SnR2. In addition to the multinuclear NMR spectroscopic data for all new compounds, X-ray structures of [OPO]SnCl2(THF), [OPO]SnMe2, and [OPO]Sn(n-Bu)2 are presented. %I ACS Publications
