Synthesis and termal stability
of heterometallic coordination compounds as precursors of rare earth element
nicelates
Abstract
Solvent
influence on the solid products composition was investigated by example of REE
nitrates and square-planar complexes of nickel(II) with Schiff bases Ni(SB)
interaction. The composition of solid REE-Ni heterometallic products was
investigated by X-ray fluorescent analysis and elemental (C, H, N) analysis. It
was shown that heterometallic complexes could be obtained in individual state
from labile Ln(NO3)3 – Ni(SB) systems, and in case of
more dentate ligands, Ni(mosalen), only bimetallic compounds are formed. The
trimetallic complexes were obtained in the case of Ni(salen) via solvent
selection. The bimetallic complexes are of interest due to the possibility of
their use as REE nickelates precursors.
