Abstract:
During outstanding research in the late 1950s in Munich, which led to the development of the Wacker process for converting ethene into acetaldehyde by catalysis of PdCl 2 , black insoluble nitrosyl‐palladium chloride (PdCl(NO)) was obtained. More than sixty years after its first synthesis, its crystal structure was now determined by X‐ray diffraction. PdCl(NO) ( mP 16, P 2 1 / c , a =10.2684(5), b =4.0737(2), c =7.8456(4) Å, β =111.125(1)°, wR2 =0.0572) consists of distorted Pd 4 Cl 4 octagons in chair arrangement to which four distorted Pd 2 Cl 2 squares are annulated on every second edge. In this arrangement each of the two Pd atoms of the squares are connected to one N−O group, bonded alternatively up and down to the Pd atoms with a Pd−N−O angle of 129°. Such a square has the composition of the dimer which was found in the mass spectrum at 343.6 m/e. The octagons with four squares are interconnected to corrugated layers in the b ‐ c ‐plane as a two‐dimensional polymer.
