โฆ Synopsis
The ternary selenide Pb 6 Sb 6 Se 17 was synthesized hydrothermally from the binaries (PbSe and Sb 2 Se 3 ) and crystallizes in the orthorhombic space group Pbam (a = 15.835(3), b = 24.043(5), c = 4.134(2)A ร , Z = 2). The main building blocks of the crystal structure are ribbons made of square pyramidal [(Pb,Sb)Se 5 ] groups running along [010].
