摘要：

2H-CuFeO2, M(r) = 151.39, hexagonal, P6(3)/mmc, a = 3.035 (1), c = 11.449 (3) angstrom, V = 91.33 angstrom 3, Z = 2, D(x) = 5.50 Mg m-3, lambda(Mo K-alpha) = 0.71073 angstrom, mu = 18.6 mm-1, F(000) = 142, room temperature, R(F) = 0.033 for 173 independent reflections with F(o) > 3-sigma(F(o)) and 9 variables. Edge sharing FeO6 octahedra [point symmetry 3mBAR, Fe-O = 2.028 (1) angstrom] form brucite-like layers in (00.1) which are linked by linear [2] coordinated Cu atoms [point symmetry 6m2BAR, Cu-O = 1.842 (2) angstrom]. 2H-CuFeO2 is a polytype of delafossite (3R-CuFeO2).
