摘要：

A new Ti(III) phosphate, Mg3Ti4P6O24, has been isolated; its structure has been determined from a single-crystal X-ray diffraction study. The triclinic cell, space groupP-1, is characterized by the following parameters:a = 6.9311(8)Å,b = 7.9616(5)Å,c = 9.4299(14)Å, α = 67.614(9)°, β = 69.348(12)°, γ = 79.327(8)°. The framework consists of (Ti, Mg)O6 isolated octahedra, Ti2O10 and (Ti, Mg)2O10 octahedral units sharing their corners and linked via PO4 tetrahedra. The M2O10 units are formed of two edge-sharing MO6 octahedra. The remaining Mg are linked to five oxygen atoms which delimit a bipyramid. The relationships between this structure and those of vanadophosphates are studied. © 1990 Academic Press, Inc.
