• Crystal structures of Pb(MoO 2) 2(PO 4) 2 and Ba(MoO 2) 2(PO 4) 2 were determined. Both compounds contain the molybdyl group MoO 2. The monoclinic unit-cell parameters are a = 6.353(7), b = 12.289(4), c = 11.800 Å, β = 92°56(6), and Z = 4 for the lead salt and a = 6.383(8), b = 7.142(7), c = 9.953(8) Å, β = 95°46(8), and Z = 2 for the barium salt. P2 1 c is the common space group. The R values are respectively R = 0.027 and R = 0.031 for 1964 and 1714 independent reflections. The frameworks built up by a three-dimensional network of monophosphate PO 4 and molybdyl MoO 2 groups are similar, characterized mainly by corner-sharing PO 4 and MoO 6 polyhedra. Two oxygen atoms of each MoO 6 group are bonded to the molybdenum atom only as in other molybdyl salts.
