Abstract

Single crystals of the mixed metal diphosphates PbCo3(P2O7)2 (1) and PbFe3(P2O7)2 (II) have been prepared by direct fusion and characterized by single-crystal X-ray diffraction, for PbCo3(P2O7)2 (I), a = 7.275(5), b = 7.725(11), c = 9.511(4)Å, β = 111.89(4)°, monoclinic space group P21/c, V = 509.3(5) Å3, dcalC = 4.768 g cm-3, Z = 2, R/Rw = 3.9/5.1% for 1192 observed reflections. For PbFe3(P2O7)2 (II), a = 7.487(1), b = 7.739(1), c = 9.516(2) Å, β = 111.95(1)°, monoclinic space group P21/c, V = 511.4(2)Å3, dcalC = 4.693 g cm-3, Z = 2, R/Rw = 4.13/4.87% for 1153 observed reflections. (I) and (II) are isotypical with PbNi3(P2O7)2 and SrNi3(P2O7)2. The solid lattice is characterized by layers of P2O4-7 groups, parallel to the crystallographic plane (001) and joined by Pb2+ and Co2+ ions in (I) and Pb2+ and Fe2+ ions in (II). Lead is seen surrounded by eight oxygen atoms whereas the transition elements are found in chains of linked trimers extending in the [010] direction [Co-Co 3.182(3) and 3.256(3) Å ; Fe-Fe, 3.186(3) and 3.264 (3) Å] with distorted octahedral geometry at each metal atom.
