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 C2h5-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+.
