ChemInform Abstract: Al₁₅Ge₄Ni₃: A New Intergrowth Structure with Cu₃Au‐ and CaF₂‐Type Building Blocks.

Abstract

Blocks. -The new title compound is prepared by arc melting of the elements followed by annealing (alumina crucible in evacuated silica tube, 430 C, 28 d). Al 15Ge4Ni3 crystallizes in the cubic space group I43m with Z = 4 (single crystal XRD) and shows a three-dimensional network of CsF 2-type units, formed by Ni and Al atoms, which is interspaced by {Al 6Ge8} clusters resembling unit cells of the Cu3Au-type. Both structural motifs are connected by Al-Ge bonds. -(REICHMANN, T. L.; JANDL, I.; EFFENBERGER, H. S.; HERZIG, P.; RICHTER*, K. W.; J. Solid State Chem. 225 (2015) 240-248, http://dx.
