Abstract
- The title complex, [Li<subscript>2</subscript>(D<subscript>2</subscript>O)<subscript>6</subscript>][Li(C<subscript>9</subscript>H<subscript>27</subscript>SSiO<subscript>3</subscript>)<subscript>2</subscript>]<subscript>2</subscript>·2D<subscript>2</subscript>O, is the first compound with an S— M bond ( M = alkali metal) within an unusual type of lithate anion, [Li(S R)<subscript>2</subscript>]<superscript>−</superscript> {where R is Si[OC(CH<subscript>3</subscript>)<subscript>3</subscript>]<subscript>3</subscript>}. There is a centre of symmetry located in the middle of the Li<subscript>2</subscript>O<subscript>2</subscript> ring of the cation. All Li atoms are four-coordinate, with LiO<subscript>4</subscript> (cations) and LiO<subscript>2</subscript>S<subscript>2</subscript> (anions) cores. The singly charged [Li(S R)<subscript>2</subscript>]<superscript>−</superscript> anions are well separated from the doubly charged [Li<subscript>2</subscript>(D<subscript>2</subscript>O)<subscript>6</subscript>]<superscript>2+</superscript> cations; the distance between Li atoms from differently charged ions is greater than 5 Å. Both ion types are held within an extended network of O—D⋯O and O—D⋯S hydrogen bonds. [ABSTRACT FROM AUTHOR]
