✦ Synopsis

The new compounds BiMn 2 PO 6 , BiMn 2 AsO 6 , and BiMn 2 VO 6 have been prepared and shown to be structurally related to several other BiA 2 MO 6 compounds. The structure of BiMn 2 PO 6 was refined from neutron powder diffraction data in space group Pnma with a=12.04 ( A, b=5.37 ( A, c=8.13 ( A, and Z=4. It contains (BiO 2 ) 1Γ€ chains and (PO 4 ) 3Γ€ tetrahedra. The observed fivefold coordination for the Mn 2+ cations is unusual for Mn in this oxidation state. # 2002 Elsevier Science (USA)
