Description
Summary:In contrast to the ubiquity of transition‐metal carbonyl, and (to a lesser extent) thiocarbonyl complexes, transition‐metal complexes of carbon monoselenide LnMCSe and monotelluride LnMCTe remain scarce. The last few years, however, have seen notable steps towards expanding this chemistry, specifically with regards to new systematic studies on homologous sets of chalcocarbonyl complexes LnMCE (E=O, S, Se, Te), the first reports of new bi‐ and polynuclear CSe and CTe bridging complexes and a confluence with metal carbido chemistry. Herein the properties, syntheses and reactions of these rare but fundamentally intriguing compounds are discussed. Distinguished d‐complexes: Recent developments in the chemistry of transition metal selenocarbonyl (LnMCSe) and tellurocarbonyl (LnMCTe) complexes have provided new insights into how the heavier chalcocarbonyls distinguish themselves from the more commonly encountered carbonyl (CO) and thiocarbonyl (CS) ligands.
