Synthesis and
crystal structure of the novel complex cobalt and nickel oxide,
Sr2.25Y0.75Co1.25Ni0.75O6.84
Abstract
Novel
complex cobalt and nickel oxide Sr2,25Y0,75Co1,25Ni0,75O6,84
has been synthesized using liquid citrates route. Oxygen content was determined
by iodometric titration. Crystal structure of the compound was refined using
X-ray powder diffraction data (a = 3,7951(2), c = 19,700(1) E,
c2
= 1,15, RF2 = 0,0586, Rp
= 0,0365, Rwp =
0,0462). Sr2,25Y0,75Co1,25Ni0,75O6,84
has a structure of the second member of Ruddlesden–Popper series An+1BnO3n+1.
