    abstract = "Abstract: The crystal structure (R = 0.0750) of fiedlerite-1A Pb3Cl4F (OH) · H2O from ancient slags of Lavrion (Greece) was studied on a single crystal. The mineral is triclinic, a = 8.5741 (7) Å, b = 8.0480 (5) Å, c = 7.2695 (4) Å, α = 90.087 (5), β = 102.126 (6), γ = 103.424 (6)°, V = 476.37 (6) Å3, Z = 2. The Pb2+ cations center the Pb(1)F(H2O)Cl6, Pb(2)(OH)2FCl5, and Pb(3)(OH)F2Cl5 bicapped trigonal prisms. In the structure there is an additional position Pb', filled by 10% with Pb2+. There are two main structural fragments alternating along the a axis: (100) layers of Pb(2)- and Pb(3)-centred polyhedra and zigzag chains, stretched along the b axis formed by Pb(1)-centred polyhedra sharing common edges. The IR spectrum of fiederlite-1A is given. © 2019, Pleiades Publishing, Ltd."
