Ca(4)As(3) – a new binary calcium arsenide

The crystal structure of the binary compound tetra­calcium triarsenide, Ca(4)As(3), was investigated by single-crystal X-ray diffraction. Ca(4)As(3) crystallizes in the Ba(4)P(3) structure type and is thus a homologue of isotypic Sr(4)As(3). The unit cell contains 32 Ca(2+) cations, 16 As(3−) isolat...

description The crystal structure of the binary compound tetra­calcium triarsenide, Ca(4)As(3), was investigated by single-crystal X-ray diffraction. Ca(4)As(3) crystallizes in the Ba(4)P(3) structure type and is thus a homologue of isotypic Sr(4)As(3). The unit cell contains 32 Ca(2+) cations, 16 As(3−) isolated anions and four centrosymmetric [As(2)](4–) dumbbells. The As atoms in each of the dumbbells are connected by a single bond, thus this calcium arsenide is a Zintl phase.
