Ba3Si4P6, eine neue Zintlphase mit vernetzten Si4P5-Käfigen / On Ba3Si4P6, a New Zintl Phase with Connected Si4P5 Cages

Abstract

The new compound Ba3Si4P6 crystallizes in the monoclinic system, space group P21/m(No.11) with the lattice constants a = 1153.7(3) pm, b = 728.1(2) pm, c=752.7(2) pm, β = 99.41(5)°. Si4P5 cages are connected by Si chains and P bridges to corrugated two-dimensional nets between which the Ba ions are located. The compound is a Zintl phase and therefore belongs to the valence compounds.
