Structure investigations of Tl(I)-arsenates(V): Tl3(AsO4), Tl2Cu(I)(AsO4) and TlCu(II)2(AsO4)(AsO3OH)

Abstract

Abstract The three Tl(I)-arsenates(V) Tl3AsO4) [a = 8.517(3) Å, c = 5.233(2) Å, space group P63, Z = 2], Tl2Cu(I)(AsO4) [a = 6.000(3) Å, = 5.343(2) Å, c = 8.616(3) Å, β = 98.05(3)°, space group P21, Z = 2], and TlCu(II)2(AsO4)(AsO3OH) [a = 6.407(2) Å, b = 11.245(4) Å, c = 10.173(3) Å, β = 98.64(2)°], space group P21/c, Z = 4] have been synthesized under hydrothermal conditions. Their structures were determined from single crystal X-ray diffraction data.
