Abstract

The intermetallic compound V₂Al₅Ge₅ grown from Al flux is reported. V₂Al₅Ge₅: orthorhombic, Cmcm, a = 5.4072(10), b = 12.978(2), and c = 11.362(2) Å, the structure features distorted pentagonal prismatic columns defined by Al and Ge atoms. Vanadium atoms occupy the central axis of columns forming a chain with long–short alternation of V–V bonds. This compound is resistant to air oxidation up to 500 °C.
