V2Al5Ge5: first ternary intermetallic in the V–Al–Ge system accessible in liquid aluminium†
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
