Abstract

The compound Na₂Ti₂Se₈ has been prepared through the reaction of Ti metal with a Na₂Se/Se flux at 345 °C. The compound crystallizes with four formula units in space group C_2h⁵-P2₁/c of the monoclinic system in a cell of dimensions a = 12.841 (7) Å, b = 7.146 (4) Å, c = 12.994 (8) Å, β = 106.18 (2)° at -160 °C. The structure contains infinite, one-dimensional Ti/Se chains that run parallel to the c axis. In these chains the Ti centers are seven-coordinate. These chains are isolated from one another by Na⁺ ions. When the Se-Se bonds are taken into account, the composition of the chain is (Formula Omited) and the compound contains Ti⁴⁺.
