摘要：
The structure of Na2Ti2Sb2O has been investigated by temperature-dependent powder neutron diffraction. Na2Ti2Sb2O crystallizes in I4/mmm symmetry. The structure of this phase can be viewed as an anti-K2NiF4 type where Ti3+ ion is located between two oxygen atoms forming a square-planar lattice. Powder neutron diffraction studies of Na2Ti2Sb2O indicate that this compound has a structural distortion in the [Ti2Sb2O](2-) layer at T approximate to 1120 K, This transition corresponds well to the previously reported anomalous transition temperature of the magnetic susceptibility and electronic resistivity, Several models to explain the data are presented and discussed, (C) 2000 Academic Press.
