Abstract

AgBiI4 and Ag3BiI6 were synthesized by solvothermal reaction from AgI and BiI3 in diluted HI-solution (20 %) at a temperature of 160 degrees C. The greyish-black crystals grow as octahedra (Ag-BiI4) or hexagonal/trigonal platelets (Ag3BiI6). AgBiI4 crystallizes in space group Fd (3) over barm with a = 1222.3(1) pm (300 K) and Z = 8 whereas Ag3BiI6 shows the space group R (3) over barm with a = ...
