Syntheses and X-ray crystal structures of lithium and chromium(II) complexes of the tri-t-butylmethoxide ligand

Abstract

The syntheses and X-ray crystal structures of Li and Cr^II complexes of the tri-t-butylmethoxide ligand are described, these are [{Li(OCBu^t₃)(thf)}₂] and [Cr(OCBu^t₃)₂·LiCl(thf)₂](thf = tetrahydrofuran); the latter compounds has a rare distorted T-shaped geometry at chromium and when dissolved in n-hexane gives LiCl and a complex that analyses as [Cr(OCBu^t₃)₂(thf)₂].
