LiBSi2: A tetrahedral semiconductor framework from boron and silicon atoms bearing lithium atoms in the channels

<p>Silicon swallows up boron: The novel open tetrahedral framework structure (OTF) of the Zintl phase LiBSi2 was made by applying high pressure to a mixture of LiB and elemental silicon. The compound represents a new topology in the B-Si net (called tum), which hosts Li atoms in the channels (see picture). LiBSi2 is the first example where B and Siatoms form an ordered common framework structure with B engaged exclusively in heteronuclear B-Si contacts. Copyright © 2013 WILEY-VCH Verlag GmbH & Co.
