Crystal structures of the silver iodide sulfates Ag₃ISO₄ and Ag₄I₂SO₄.

ABSTRACT: The crystal structures of two phases in the AgI-Ag₂SO₄ system, Ag₃ISO₄(AgI:Ag₂SO₄ = 1:1; systematic name: tris-ilver iodide sulfate), and Ag₄I₂SO₄ (AgI:Ag₂SO₄ = 2:1; systematic name: tetra-silver diiodide sulfate), were determined by single-crystal X-ray diffraction. The crystal structure model of Ag₃ISO₄ contains triangularly arranged Ag atoms in zigzag ladder chains extending parallel to the a axis. The Ag zigzag ladder chains alternate with rows of SO₄ groups, while iodine atoms are accommodated within the concavities of the zigzag ladders. The crystal structure of Ag₄I₂SO₄ was refined using a sp
