KMnCuTe₂: a layered antiferromagnetic semiconductor with long metal-metal distance.

ABSTRACT: The magnetic semiconductor in a two-dimensional system is a major subject for both theoretical and experimental investigations. Here we report the synthesis of a new quaternary manganese chalcogenide KMnCuTe₂, which shows layered structure and antiferromagnetic (AFM) semiconducting features. Single crystals of KMnCuTe₂ were obtained using a self-flux method and based on single-crystal X-ray diffraction, KMnCuTe₂ adopts the ThCr₂Si₂-type structure composed of edge-sharing tetrahedral layers separated by K⁺ cations. The Mn and Cu atoms randomly distribute in the centre of tetrahedral units. Attributed to the large radius of Te, KMnCuTe₂ has large lattice parameters (a = 4.3115(3) Å and c = 14.9360(20)
