Die Kristallstruktur des Nitridotetrachloromolybdat(VI), [(C6H5)4As] [MoNCl4], und die Hydrolyse zum isotypen Oxotetrachloromolybdat(V), [(C6H6)4As] [MoOCl4] / The Crystal Structure of the Nitrido Tetrachloro Molybdate(VI), [(C6H5)4As][MoNCl4], and the Hydrolysis to the Isotypic Oxo Tetrachloro Molybdate(V), [(C6H5)4As][MoOCl4]

Abstract

The partial hydrolysis of AsPh₄[MoNCl₄] (AsPh₄ = [(C₆H₅)₄As]) leads to AsPh₄[MoOCl₄]. Both salts crystallize isotypic in the tetragonal space group P 4/n with Z = 2. The crystal structures are built up by AsPh₄ cations and square pyramidal [MoXCl₄] anions with the symmetry C_4v. The Mo—N distance of 166 pm and the slightly longer Mo-O distance of 171 pm indicate strong π-bonding.
