Cover Picture: Lithium [Bis{benzoyl‐W(CO)5}(μ2‐hydrogen)] − A Charge‐Assisted H+‐Bridged Organometallic Complex Prepared by Selective Li+ Ion Replacement (Eur. J. Inorg. Chem. 21/2003)

Abstract

AbstractThe cover picture shows the crystal structure of lithium bis[benzoyl‐W(CO)5][μ2‐hydrogen] (orange: tungsten; red: oxygen; blue: lithium; grey: carbon), a new class of hydrogen‐bridged organometallic complexes exhibiting strong, charge assisted hydrogen bonds between anionic metal−acyl moieties in Fischer‐type carbene precursors. The novel cation‐exchange procedure used here could find application in future organometallic crystal engineering studies involving carbonylmetal fragments. Details are discussed in the article by H. G. Raubenheimer et al. on p. 3861 ff. Dedicated to E. O. Fischer on the occasion of his 85th birthday
