摘要: A molybdenum(V) monophosphate containing lead has been synthesized for the first time. This new phase Pb3(MoO)3(PO4)5 crystallizes in Pnma space group with a=14.280(1) A, b=15.679(1) and c=8.129(1) A. The crystal structure was refined up to R=0.0406 Rw=0.0446. original three-dimensionnal framework of this compound, [Mo3P5O23]∞, can be described by assemblage [Mo3P5O28]∞ ribbons running along b→ forming elliptic tunnels where Pb2+ cations are located. topological analogy aeschynite is emphasized. stereoactivity 6s2 lone pair discussed.
