Synthesis and X-ray crystal structure of the first manganese(II) dialkylamido complex: {Mn3(µ-NEt2)6(µ-Cl)2[Li(THF)2]2}·(C7H16)(THF = tetrahydrofuran)

Abstract
Reaction of MnCl2 with LiNEt2 in tetrahydrofuran(THF)/n-heptane afforded the pentanuclear title complex {Mn3(µ-NEt2)6(µ-Cl)2[Li(THF)]2}, whose molecular structure shows the presence of three tetrahedrally co-ordinated manganese atoms, joined by four bridging NEt2 groups [with Mn–N bond distances ranging from 2.089(4) to 2.203(4)Å, the Mn ⋯ Mn distance being 2.917(1)Å], and two Li(THF)2 moieties terminally bonded via diethylamido and chloride bridges.
