3D and 2D representations of the elastic properties of TlBaCl3: (a) 3D and (b) 2D projections of Young’s modulus, showing moderate anisotropy with a four-lobed pattern in the XY plane; (c) 3D and (d) 2D projections of shear modulus, indicating significant directional variation and higher anisotropy; (e) 3D and (f) 2D projections of Poisson’s ratio, displaying strong anisotropy with complex lobed structures.
