Abstract

The layered mixed anion compound with the formula [Li0.85Fe0.15OH][FeS] was synthesized via a facile hydrothermal method. [Li0.85Fe0.15OH][FeS], which is determined by single crystal X-ray diffraction and refined by the SHELXTL program, crystallizes in the tetragonal space group of P4/nmm (a = b = 3.6886(3) Å, c = 8.915(1) Å, V = 121.29(2) Å3, Z = 2). The structure features alternatively packed anti-PbO-like [Li0.85Fe0.15OH] and anti-PbO [FeS] layers. The sample was characterized by Field Emission Scanning Electron Microscopy (FESEM) and High-Resolution Transmission Electron Microscopy (HRTEM). Powder X-ray diffraction results confirm the phase purity of the as-synthesized crystals. Temperature-dependent measurements of magnetic susceptibility reveal the presence of a paramagnetic-to-ferromagnetic phase transition around 50 K, accompanied by the metal-to-semiconductor phase transition in the temperature-dependent resistance of the [Li0.85Fe0.15OH][FeS] single crystal.
