Abstract
Single crystals of two forms of zinc orthoarsenate (alpha-Zn-3(ASO(4)) (2) (I) and beta-Zn-3(AsO4)(2) (II)) have been prepared by flux techni ques. Both compounds crystallize monoclinically, space groups (I): C-2 h(5)-P2(1)/c, (II): C-2h(5)-P2(1)/n, with the lattice parameters (I): a = 6.306(2), b = 8.652(2), c = 11.321(4) Angstrom, beta = 92.25(5) de grees, Z = 4 and (II): a = 5.281(1), b = 8.494(2), c = 7.726(3) Angstr om, beta = 96.39(3)degrees, Z = 2. alpha-Zn-3(AsO4)2 is isotypic to I- Cu-3(AsO4)(2) and beta-Zn-3(AsO4)(2) to gamma-Zn-3(PO4)(2). Similariti es and differences of the crystal structures are discussed.
