A novel molybdenum(V) monophosphate containing bromine and mixed valent lead, Pb2+(Pb4+0)Br(Mo5+0)2(P04)3, has been synthesized for the first time. It crystallizes in the orthorhombic space group Fdd2 with a = 31.721(7) Ã…, b = 12.931(2) Ã…, c = 12.905(2) Ã…. Its frameworks built up from [Mo[sup]2[/sup]P[sup]2[/sup]O[sup]12[/sup]]∞ perovskite type layers connected through phosphate groups, delimits tunnels in which the Pb[sub]2+[/sub] and the Pb[sub]4+[/sub] cations and the Br[sub]-[/sub] anions are sitting. The Pb[sub]4[/sub]+ specie is connected to one isolated oxygen atom via a double bond forming a Pb=O 'Leadyl' group. The divalent lead ions bonded to the bromine ions form infinite -Pb-Br- ribbons running along b in the tunnel. On these ribbons are scratched the Leadyl groups. (English)
