Synthesis, crystal structure, and atomic interactions in NbGePt

Abstract

- Abstract The new ternary compound NbGePt was prepared by direct reaction of the elements. The crystal structure was investigated by single-crystal X-ray diffraction methods: structure type TiNiSi, Pearson symbol oP 12, space group Pnma , a = 6.4487(3) Å, b = 3.9300(2) Å, c = 7.5065(4) Å, Z = 4. Analysis of chemical bonding by the electron density/electron localizability approach revealed, beside the expected Ge–Pt bonds, strong covalent interactions between Nb and Ge. Graphical abstrac
