Abstract

Syntheses and single-crystal X-ray structural results are reported for three new mixed diphosphates of the family A^I₂B^II₃(P₂O₇)₂; Ag₂Co₃(P₂O₇)₂ (I), Ag₂Mn₃(P₂O₇)₂ (II), and Na₂Cd₃(P₂O₇)₂ (III). All crystallize in the triclinic system, space group P1 bar: (I) a = 5.351(4), b = 6.375(4), c = 16.532(4) A, a = 80.83(6) β = 81.45(4), y = 72.87(5)°, V = 528.9(6) Å³, Z = 2, D_calc = 4.649 mg/m³, R/Rw = 0.0428/0.0548 for 3949 obs. refins; (II) a = 5.432(7), b = 6.619(6), c = 16.51(3) Å, α = 80.78(8) β = 82.43(9), γ = 72.82(7)°, V = 557.7(13) Å³, Z = 2, D_calc = 4.338 mg/m³, R/Rw = 0.0679/0.1303 for 2100 obs. refins and (III) a = 5.67(3), b = 7.08(4), c = 7.90(4) Å, a = 77.0(2), β = 82.5(2), y = 67.8(2)°, V = 286(3) Å³, Z= 2, D_calc = 4.249 mg/m³, R/Rw = 0.0307/0.0342 for 1945 obs. reflns. (I) and (II) are isostructural but (III) is of a different type. All three structures are characterized by layers of P₂O₇ groups alternating with layers of mixed metal atoms. Differences are seen in the conglomerate bonding patterns of B atoms and in the irregular geometry of Ag in (I) and (II) compared to the octahedral bonding seen for Na in (III). The differences in structure may be understood in terms of the ratios of the ionic radii of A and B atoms.
