Versatile Method for Preparing Two-Dimensional Metal Dihalides.

ABSTRACT: Ever since the ground-breaking isolation of graphene, numerous two-dimensional (2D) materials have emerged with 2D metal dihalides gaining significant attention due to their intriguing electrical and magnetic properties. In this study, we introduce an innovative approach via anhydrous solvent-induced recrystallization of bulk powders to obtain crystals of metal dihalides (MX₂, with M = Cu, Ni, Co and X = Br, Cl, I), which can be exfoliated to 2D flakes. We demonstrate the effectiveness of our method using CuBr₂ as an example, which forms large layered crystals. We investigate the structural properties of both the bulk and 2D CuBr₂ using X-ray diffraction, along with Raman scattering and optical spectroscopy, revealing its quasi-1D chain structure, wh
