- X-ray diffraction on single crystal performed on Gd2Sc3Si4 reveals that this ternary silicide crystallizes as Gd2Sc3Ge4 in the orthorhombic Ce2Sc3Si4-type with a small deficiency in gadolinium leading to the formula Gd1.88(1)Sc3Si4. The structure is formed by [Gd2Sc3Si4] slabs with Si-Si interslab covalent bonds. The investigation of the Gd2Sc3Si4 and Gd2Sc3Ge4 compounds by magnetization, electrical resistivity and specific heat measurements reveals their antiferromagnetic behaviors; Gd2Sc3Si5 having a Néel temperature (48-52 K) higher than that observed (22-23 K) for Gd2Sc3Ge4.
