摘要：
The structure of 1T-Li2NiO2 from profile refinement of powder neutron diffraction data is reported. The compound has space group P-3m1, with a = 3.0954(9) angstrom and c = 5.070(1) angstrom. Hexagonally close-packed layers of oxygen alternate with metal atom layers in the sequence O-Ni-O-Li-O-Ni-O-Li... . The nickel atoms fill the octahedral interstices between the more closely spaced pairs of O layers and the Li atoms fill all the tetrahedral sites between the alternate, more separated, oxygen layers.
