I2-HfCuGeaAI2-HfCuGeaA new polymorph of HfCuGe with a novel structure type

The structure and elementary physical properties of a new intermetallic compound, I2-HfCuGeI2-HfCuGe, are reported. I2-HfCuGeI2-HfCuGe has a tetragonal structure (space group I4/mmm) with lattice constants of a=3.7634(11)A and c=13.499(4) A. The structure, which consists of double layers of Hf stack...

Description
Summary:The structure and elementary physical properties of a new intermetallic compound, I2-HfCuGeI2-HfCuGe, are reported. I2-HfCuGeI2-HfCuGe has a tetragonal structure (space group I4/mmm) with lattice constants of a=3.7634(11)A and c=13.499(4) A. The structure, which consists of double layers of Hf stacked with edge-sharing CuGe4 squares, is not typical for intermetallic compounds and appears to be a new structure type. The compound is a weak paramagnet and a normal metal down to 0.4 K.
