“…In contrast, in the presence of the bulkier IPr ligand, M ··· M contacts are essentially non‐bonding. This gives further support to the conclusion that metallophilic interactions are rather soft and strongly depends on the steric properties of the ancillary ligands employed in such complexes …”

“…Heterometallic complexes and clusters containing coinage metals in the +1 oxidation state were very attractive since they presented heterometallic bonds and metallophilic interactions, that is, attractive interactions between the closed shell d 10 centres Aurophilicity was investigated at first, in relation also to relativistic phenomena, followed by argentophilicity and cuprophilicity , . Several homoleptic and heteroleptic carbonyl clusters containing 2–8 coinage metals (also mixed ones) supported by Fe, Co, Mo, V and Ru carbonyl moieties were reported , , . These allowed to study the effects of the coinage metal, heterometal and ancillary ligands on the bonding within such heterometallic clusters.…”

The [Fe(CO)4{M(NHC)}]– (M = Cu, NHC = IMes, 1; M = Cu, NHC = IPr, 2; M = Ag, NHC = IMes, 3; M = Ag, NHC = IPr, 4; IMes = C3N2H2(C6H2Me3)2; IPr = C3N2H2(C6H3iPr2)2) mono‐anions were obtained from the reaction of Na2[Fe(CO)4]·2thf with one equivalent of M(NHC)Cl (M = Cu, Ag; NHC = IMes, IPr) in dmso. Furthermore, the reaction of Na2[Fe(CO)4]·2thf with two equivalents of M(NHC)Cl in thf afforded the neutral compounds Fe(CO)4{M(NHC)}2 (M = Cu, NHC = IMes, 11; M = Cu, NHC = IPr, 12; M = Ag, NHC = IMes, 13; M = Ag, NHC = IPr, 14). 2 and 4 further reacted with one equivalent of M(IPr)Cl (M = Cu, Ag, Au) resulting in the trimetallic clusters Fe(CO)4{Cu(IPr)}{Ag(IPr)} (18), Fe(CO)4{Cu(IPr)}{Au(IPr)} (19), and Fe(CO)4{Ag(IPr)}{Au(IPr)} (20). 1–4, 11–14 and 18–20 have been spectroscopically characterized by IR, 1H and13C{1H} NMR techniques. The molecular structures of 2, 12, 18, 19 and 20 have been determined through single‐crystal X‐ray diffraction. The structure, bonding and stability of the copper and silver IMes derivatives were compared to the related Fe‐Au clusters previously reported on the basis of theoretical calculations. Stability of the Fe–M bonds decreases in the order Au > Cu > Ag, and the same trend was found for what concerns the M‐IMes interactions. The decomposition products of 1–4, 11–14 and 18–20 have been studied allowing, among the others, the structural characterization of the new species [Fe2(CO)8{Ag(IPr)}]– (10) and Fe(CO)4(CH2IMes) (21).

“…In particular, it seemed that the bulkier IPr ligand provided a better steric protection to the LUMO localized on the AuNHC fragment than IMes. Overall, molecular carbonyl clusters might be considered as valuable platforms for the study of M–M and M‐ligand interaction as well as their related reactivities , , …”

“…These may be viewed as the result of the addition of [AuL] + (L = phosphine, N ‐heterocyclic carbene) fragments to the surface of an iron carbonyl cluster anion, i.e., [Fe(CO) 4 ] 2– , [Fe 3 (CO) 11 ] 2– , [Fe 2 (CO) 8 ] 2– , [Fe 3 E(CO) 9 ] 2– (E= O, S, Te), [HFe 4 (CO) 12 ] 3– , [Fe 4 C(CO) 12 ] 2– , [Fe 5 C(CO) 14 ] 2– , [Fe 6 C(CO) 16 ] 2– and [Fe 6 C(CO) 15 ] 4– . These reactions have been widely employed in order to selectively increase of a few units the nuclearity of the clusters , . Moreover, based on the isolobal analogy between [AuL] + and H + , the former fragments have been used in order to have information on the protonation sites of anionic clusters .…”

The reaction of Collman's reagent Na 2 [Fe(CO) 4 ]·2thf with one equivalent of Au(NHC)Cl (NHC = IMes, IPr; IMes = C 3 N 2 H 2 (C 6 H 2 Me 3 ) 2 ; IPr = C 3 N 2 H 2 (C 6 H 3 iPr 2 ) 2 ) in dmso resulted in the [Fe(CO) 4 (AuNHC)] -(NHC = IMes, 1; IPr, 2) mono-anions. 1-2 further reacted with Au(NHC)Cl or Au(PPh 3 )Cl affording the neutral complexes Fe(CO) 4 (AuNHC) 2 (NHC = IMes, 3; IPr, 4), Fe(CO) 4 (AuIMes)(AuIPr) (5) and Fe(CO) 4 (AuNHC)(AuPPh 3 ) (NHC = IMes, 6; IPr, 7). 1-7 have been spectroscopically characterized by IR, 1 H, 13 C{ 1 H} and 31 P{ 1 H} NMR techniques. Moreover, the molecular structures of 1, 2, 4, 6 and 7 have been determined through single-crystal X-ray diffraction as their [NMe 4 ][Fe(CO) 4 -[a] Dipartimento
