Über [CO4S3(SO)(CN)12]8- : bemerkenswerte Bildung eines Clusters und eines „SO“-Liganden sowie Relevanz zum Promotor-Effekt bei der HDS-Katalyse / [Co4S3(SO)(CN)12]8-: A Remarkable Formation of a Cluster and a “SO ” Ligand and its Relevance to the Promotor Effect of HDS Catalysis

Abstract

Abstract The preparation of K8[Co4S3(SO)(CN)12] • 4 H2O (by cyanolysis of “cobalt sulfide”) and its properties (vibrational, UV/VIS and ESCA spectra, magnetic and thermogravimetric data, and crystal structure) are reported. The formation of a “SO " ligand through air oxidation is discussed with regard to the promoting effect of Co in the CoMoS phase of the hydrodesulfurization (HDS) catalyst
