    Description / Table of Contents: MoNCl3 crystallises in the triclinic space group PI with 4 formula units per unit cell, the lattice constants being a = 9.14, b = 7.67, c = 8.15 Å; α = 108.8°, β = 99.3° and γ = 108.6°. The crystal structure was solved by means of three-dimensional PATTERSON and FOURIER syntheses and refined by the method of least squares to a reliability index of 5.8%. The structure is built up from two slightly different kinds of MoNCl3 molecules having Mo—N triple bonds (Mo—N distances 1.64 and 1.67 Å). Each N atom is coordinated to the Mo atom of a neighbouring molecule in such a way that tetramers with the pseudosymmetry 4/m are formed. The tetramers are linked together by bridging Cl atoms so that puckered layers parallel to (010) result.
    Notes: MoNCl3 kristallisiert triklin (Raumgruppe PI) mit 4 Formeleinheiten pro Elementarzelle und den Gitterkonstanten a = 9,14, b = 7,67, c = 8,15 Å; α = 108,8°, β = 99,3° und γ = 108.6°. Die Kristallstruktur wurde aus dreidimensionalen PATTERSON und FOURIER-Synthesen abgeleitet und nach der Methode der kleinsten Quadrate bis zu einem Zuverlässigkeitsindex von 5,8% verfeinert. Die Struktur baut sich aus zwei wenig verschiedenen Arten von MoNCl3-Molekeln auf, die Mo—N-Dreifachbindungen enthalten (Mo—N-Abstände 1,64 und 1,67 Å). Jedes N-Atom ist in der Weise zum Mo-Atom einer Nachbarmolekel koordiniert, daß Tetramere mit der Pseudosymmetrie 4/m entstehen. Die Tetrameren sind durch Cl-Brücken lose verknüpft und bilden gewellte Schichten parallel zu (010).
