Abstract
Two Fe+ centres have been identified by ESR after X-ray irradiation at 80 K of chlorinated SrCl2 : Fe2+ crystals. Both centres, with tetragonal symmet ry, consist of an Fe+ ion with a neighbouring charged defect along the [001 ] symmetry axis. The substitutional Fe+ ion of the Fe+(I) centre is strongl y off-centre displaced in the Fe+(II) centres, in the middle of a square of four nearest neighbour chlorine ligands.
