Abstract
Magnetic susceptibility measurements and neutron powder diffraction we re performed on orthorhombic Na2TiCl4. The Ti2+ ions occupy compressed Cl-6 octahedra sharing common edges to form Ti-Cl chains along the c- axis. The powder susceptibility can be fitted using a one-dimensional S = 1 Heisenberg: model with \J\/k(B) = (58 +/- 5)K plus a Curie-Weiss contribution. Below T-N = (13.0 +/- 0.5)K, magnetic superstructure re flections show the onset of 3d antiferromagnetic order with mu = (0.89 +/- 0.05)mu(B) at 1.8 K.
