Possible Charge-Density-Wave/Spin-Density-Wave in the Layered Pnictide−Oxides: Na2Ti2Pn2O (Pn = As, Sb)
Abstract
The compounds Na2Ti2Pn2O (Pn = As, Sb) crystallize in the anti-K2NiF4 structure type in the space group, I4/mmm, with Z = 2 and the lattice parameters a = 4.0810(9) Å and c = 15.311(3) Å for the As analogue at 310 K and a = 4.160(2) Å and c = 16.558(7) Å for the Sb analogue at 150 K. The structure consists of edge-shared [Ti4/2Pn2O4/4]2- layers separated by double layers of Na+. These compounds exhibit an anomalous transition in the …
