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

The syntheses and X-ray crystal structures of Li and CrII complexes of the tri-t-butylmethoxide ligand are described, these are [{Li(OCBut3)(thf)}2] and [Cr(OCBut3)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(OCBut3)2(thf)2].
