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), b = 8.0480(5), с = 7.2695(4) Å, (a = 90.087(5), (b = 102.126(6), (g = 103.424(6)) V = 476.37(6) Å3, Z = 2. Pb2+ cations centre bicapped trigonal prisms Pb(1)F(H2O)Cl6, Pb(2)(OH)2FCl5 and Pb(3)(OH)F2Cl5. Additional Pb′site with 10% occupancy was revealed in the structure. There are two basic structure fragments alternating along the a axis: (100) layers formed by Pb(2)- and Pb(3)-centred polyhedra and elongated along the b axis zig-zag chains formed by Pb(1)-centred polyhedra sharing common edges. IR spectrum of fiedlerite-1A is given.
