Ag1.49Mn1.49IIMn1.51III(AsO4)3

A. Brahim and H. Amor

Abstract: The compound Ag1.49Mn1.49IIMn1.51III(AsO4)3 (silver manganese arsenate) was prepared by a solid-state reaction. It crystallizes in the monoclinic system in space group C2/c. The three-dimensional network is built up from MnO6 octahedra, sharing edges which are linked together by the arsenate groups (AsO4). This arrangement delimits two types of hexagonal tunnels which accommodate Ag+ cations. The compound is isostructural with the compounds X(1)X(2)M(1)M(2)2(PO4)3 of the alluaudite structure.
