Zusammenfassung

Neben dem bereits bekannten Mangansilicid Mn11Si19 (MnSi1,727) werden folgende neue Verbindungen des Typs Mn n Si2n−m nachgewiesen: Mn26Si45 (MnSi1,730), Mn15Si26 (MnSi1,733) und Mn27Si47 (MnSi1,741). Die Kristallstruktur von Mn15Si26 wird mit Hilfe von Fourier-und Differenz-Fourier-Synthesen bestimmt. Die Gitterparameter für die tetragonale Elementarzelle\((I\bar 42d--- D_{2d}^{12} )\) betragena=5,525 undc=65,55 Å.

Abstract

Besides the manganese silicide Mn11Si19 (MnSi1.727) already reported, the following compounds of the general formula Mn n Si2n−m have been observed: Mn26Si45 (MnSi1.730), Mn15Si26 (MnSi1.733), and Mn27Si47 (MnSi1.741). The crystal structure of Mn15Si26 has been determined by means of Fourier-and Fourier-difference-synthesis. The lattice parameters for the tetragonal unit cell\((I\bar 42d--- D_{2d}^{12} )\) have been found to be:a=5.525 andc=65.55 Å.
