Synthesis and magnetic properties of a quaternary compound Ba3F2MnSe3 with one-dimensional tetragonal chain structure

A new quaternary compound Ba3F2MnSe3 was synthesized by using a high-temperature solid-state reaction method in closed silica tubes at 1253 K. The compound displays an infinite one-dimensional corner-sharing MnSe3 tetragonal chain separated by 1D1∞ [Ba3F2]4 + cationic chains of the fluorite type. Magnetic susceptibility results verify the presence of the antiferromagnetic short-range order at low temperature.
