Junk, Peter C.;Leary, Stuart G.

Abstract

The syntheses and single crystal X-ray structure determinations are reported for [Li(thf)₄][SnCl₅(thf)] (1) and {[Li(Et₂O)₂]₂-(μ-Cl₂)₂-Sn^IVCl₂} (2). Compound 1 is ionic with a tetrahedral coordinated lithium cation and distorted octahedral tin (IV) atom in the anion, while compound (2) is a centrosymmetric heteronuclear double salt of LiCl and SnCl₄. [Li(thf)₄][SnCl₅(thf)] is monoclinic, P21/n, a = 11.204(1), b = 15.599(1), c = 17.720(2) Å; β = 96.734(2)°, Z = 4, R 0.0418; {[Li(Et₂O)₂]₂-(μ-Cl₂)₂-Sn^IVCl₂} is monoclinic, P2₁/n, a = 10.848(2), b = 12.764(2), c = 11.748(2) Å; β = 90.388(3)°, Z = 4, R = 0.0851.
