Synthesis, structural characterization, and coordination chemistry of imidazole-based alkylidene ketenes

Rosario Scopelliti, Kay Severin, Farzaneh Fadaei Tirani, Paul Varava, Wolfram Feuerstein

Alkylidene ketenes typically display high intrinsic reactivity, impeding isolation on a preparative scale. Herein, we report the synthesis of alkylidene ketenes by reaction of imidazole-based diazoolefins with carbon monoxide. The good thermal stability of ...

Picometer Resolution Structure of the Coordination Sphere in the Metal-Binding Site in a Metalloprotein by NMR

David Lyndon Emsley, Andrea Bertarello

Most of our understanding of chemistry derives from atomic-level structures obtained with single-crystal X-ray diffraction. Metal centers in X-ray structures of small organometallic or coordination complexes are often extremely well-defined, with errors in ...

Stabilization of the Oxidation State plus IV in Siloxide-Supported Terbium Compounds

Rosario Scopelliti, Marinella Mazzanti, Ivica Zivkovic

The synthesis of lanthanides other than cerium in the oxidation state +IV has remained a desirable but unmet target until recently, when two examples of Tb-IV with saturated coordination spheres were isolated. Here we report the third example of an isolate ...

From structure to application: studies on adenine-, pyrene- and lanthanide-based metal-organic frameworks

Andrzej Gladysiak

Metal-organic frameworks (MOFs) are coordination polymer materials in which inorganic metal ions or clusters are linked with multitopic organic ligands by means of coordination bonds. Their structural versatility allows for design of materials based on pre ...
