摘要：

NaNiFe2(AsO4)3 is the only phase of theNaMIIFe2(AsO4)3(MII =Mg, Co, Ni, Cu, Zn) that crystallizes as the homologous monoclinic Cr(III) family with space groupP21/c(C62h). Its crystallographic parameters were calculated:a = 7.06A °,b = 9.38A °,c = 19.63A °, β = 114.2° (Z = 4). The symmetry sites that Fe(III) occupies and the distortions of the FeO6 polyhedron were analyzed by Mössbauer spectroscopic measures. The IR spectrum of this compound has also been registered and the vibrational modes of the different polyhedra of the lattice have been interpreted. © 1992 Academic Press, Inc. All rights reserved.
