The new intermetallic compound Ca2As3 has been prepared and its structure determined. Ca2As3 crystallizes monoclinic, space group P2/c, Z = 8. In this compound the As-atoms form As4- and As8-chains in the ratio 1:1 in the unit cell. The building principle of the “anionic” part of the structure with respect to the Ca-contents matches with the concept of ZINTL, KLEMM and BUSMANN, so the compound belongs to the ZINTL-phases.
