Synthesis and crystal structure of two new phosphates with Alluaudite type structure: (M, Mn)3Fe(PO4)3 (M= Ca, Cd)

Show other versions (1)

Two new phosphates with alluaudite type structure (M, Mn)3Fe(PO4)3 (M= Ca, Cd), namely Ca1.54Mn1.46Fe(PO4)3 and Cd0.66Mn2.34Fe(PO4)3, has been synthesized by a solid state reaction and characterized by single-crystal X-ray diffraction. The two compounds crystallize in the monoclinic system with C2/c...
