Ruddlesden-Popper Oxyfluorides La₂Ni_1-xCu_xO₃F₂ (0 ≤ x ≤ 1): Impact of the Ni/Cu Ratio on the Structure.

ABSTRACT: Ruddlesden-Popper oxyfluorides La₂Ni_1-xCu_xO₃F₂ (0 ≤ x ≤ 1) were obtained by topochemical reaction of oxide precursors La₂Ni_1-xCu_xO₄, prepared by citrate-based soft chemistry synthesis, with polyvinylidene fluoride (PVDF) as the fluorine source. Systematic changes of the crystal structure in the oxide as well as the oxyfluoride substitution series were investigated. For 0.2 ≤ x ≤ 0.9, the oxyfluorides adopt the monoclinic (C2/c) structural distortion previously solved for the x = 0.8 compound based on neutron powder diffraction data, whereas the sample with a lower Cu content of x = 0.1 crystallizes in the orthorhombic (C
