A three body problem: a genuine heterotrimetallic molecule vs. a mixture of two parent heterobimetallic molecules

Abstract: Tetranuclear molecular precursor Li2CoNiL6 for oxide cathode materials has been shown to contain heterotrimetallic and both parent heterobimetallic molecules.

“…Cobalt is earth-abundant and many cobalt complexes have been shown to be efficient catalysts for H 2 production11,39 and hydrogenation reactions 40,41. However, bimetallic NiCo complexes have been reported only infrequently42 and the related heteronuclear hydride complexes have never been documented. In this work, we produced a heterobimetallic [Ni( ii )Co( iii )H] + hydride [(dppe)Ni(pdt)(H)CoCp*] + ( [1H] + , pdt 2– = 1,3-(CH 2 ) 3 S 2 2– , Cp* – = Me 5 C 5 – , and dppe = Ph 2 PC 2 H 4 PPh 2 ) by protonating the reduced state [(dppe)Ni(pdt)CoCp*] ( 1 ) for a catalytic proton reduction (Fig.…”

“…It should be noted here that the full replacement of Mn at only one specific site will bring about a “true” hetero tri metallic molecule, LiMnCo(thd) 5 . On the contrary, the substitution at both positions will likely result in a mixture of hetero bi metallic (LiMn 2 (thd) 5 and LiCo 2 (thd) 5 ) and hetero tri metallic species as we have recently demonstrated for the Li 2 CoNiL 6 system 54. In order to assess if the unique trinuclear molecule LiMn 2 (thd) 5 has specific preferences for accommodating cobalt in one of its two transition metal positions, theoretical calculations of thermodynamic stability for the four possible trimetal cores (Fig.…”

“…Presumably, mass spectrometry is an ideal method to provide accessible, fast, and unambiguous assessment of the presence of hetero tri metallic molecules vs. the mixture of hetero bi metallic counterparts or all of the above. It should work well when the two transition metals are well-separated in terms of their atomic masses and isotope distribution patterns, unlike the recently reported case of the Li–Co–Ni system 54. However, for successful application of mass spectrometry it is important that heterometallic molecules exhibit a certain degree of structural integrity in maintaining heterometallic ions at experimental conditions and do not undergo excessive fragmentation/recombination processes in the mass spectrometer.…”

“…Coordination chemistry of β‐diketonates opens up broad opportunities for potential practical use in modern material science. Homo‐ and heterometallic β‐diketonates are intensively studied in chemical vapour deposition (CVD) processes as precursors for nanocomposite and hybrid thin film materials,[1d], in catalysis, biological imaging and OLED technologies . Their application as memory devices and fuel cell components is reported.…”
