X-ray crystallographic and conductance study of CuNiSnO4 synthesized by two different methods

Abstract

Two new ternary oxidic compositions of CuNiSnO4 have been prepared. The ternary composition Cu2+Ni2+SnO4 in orthorhombic symmetry with lattice dimensions a0=5·773 ± 0·01 Å;b0=8·377 ± 0·01 Å;c0=10·094 ± 0·01 Å, while Cu+Ni3+SnO4 is also orthorhombic but with lattice dimensions a0=5·737 ± 0·01 Å;b0=7·125 ± 0·01 Å and c0=10·071 ± 0·01 Å. The variation of electrical conductance with temperature indicates the semiconducting nature of these compositions. Hot-probe method indicates p-type semiconduction in both the compositions © 1994 the Indian Academy of Sciences.
