2017年8月27日 · Diiron nonacarbonyl, [FeX2(CO)X9] [F e X 2 (C O) X 9], is often depicted with an Fe–Fe bond as shown at the left-hand side: The Fe—Fe bond is usually invoked in order to (1) explain the observed diamagnetism and (2) satisfy the 18-electron rule.

Structure and energetics of Fe2 (CO)8 singlet and triplet electronic states. The journal of physical chemistry. A, 111 (48), 12152-12162 (2007-11-09) The singlet and triplet state potential energy surfaces (PES) of Fe2 (CO)8 are explored by means of …

2022年4月5日 · Diiron nonacarbonyl, Fe 2 (CO) 9, was discovered in 1905 and was the third metal carbonyl to be found. It was the first to be synthesized by a photochemical route. This is a challenging material to study: it is insoluble in virtually all solvents and decomposes at 373 K …

2017年7月25日 · From the discovery of Fe 2 (CO) 9 in 1905 to the intensive post-millennium study of dithiolate-bridged diiron complexes as biomimics of the active site of [FeFe]-hydrogenases, over the past century the diiron centre has been the …

IR spectra of Fe 2 (CO) 9 shows two ν CO bands. Explain. Fe 2 (CO) 9 has two types of CO groups- three bridging and six terminals. Terminal CO groups have bond order about three and bridging CO groups have bond order about two . The bridging CO behaves as ketonic group in inorganic compounds.
