摘要 Two ternary Eu-Hf-Q (Q = S, Se) chalcogenides, EuHfSe3 (1) and Eu5Hf3S12 (2), have been synthesized by a facile solid state routine and structurally characterized by single-crystal X-ray diffraction technique. They crystallize in the orthorhombic space group Pnma (1) or hexagonal P 2m (2), and diverse Hf-Q chains exist in their 3D structures. The electronic structure of 1 is also calculated according to density functional theory.

Abstract：Two ternary Eu-Hf-Q (Q = S, Se) chalcogenides, EuHfSe3 (1) and Eu5Hf3S12 (2), have been synthesized by a facile solid state routine and structurally characterized by single-crystal X-ray diffraction technique. They crystallize in the orthorhombic space group Pnma (1) or hexagonal P 2m (2), and diverse Hf-Q chains exist in their 3D structures. The electronic structure of 1 is also calculated according to density functional theory.
