“…The potential of cluster complexes to mediate unique bond forming/breaking reactions [83] or of heterobimetallic complexes to display reactivity patterns that are unknown for their homometallic analogs, as recently observed in the dimerization of methylacrylate promoted by a Ni-Mo complex [84] is also noteworthy. The diversity provided by synthetic chemistry remains a fascinating challenge and new bonding situations continue to be discovered [85], in particular in cluster chemistry which offers unique opportunities for aesthetically pleasing mixed-metal, often dynamic molecules (Mn 4 Pd 4 helices, Fe 2 HgCu molecular torsion pendulum) [86], very large clusters [56,87], giant single-molecule magnets [88] and extended structures [89], including systems that move towards bimetallic wires [90].…”

“…9.6°). The Pd-Ag bond is very short (2.8752(5) Å ) and is even shorter than the Pd-Ag bond in [PtPdAg(l- [32], the two-dimensional cationic polymer [{Pd 3 (S 2 CNEt 2 ) 6 Ag 2 } n ] 2n+ (2.933(2) and 3.046(2) Å ) [33], the polymer [[AgPd{OCHNP(Ph 2 )}{N-(Me 2 )CH 2 C 6 H 4 }] 3 ] + (2.884(1) Å ) [34] and a heterocyclic carbene triflouroacetato AgPd 2 complex [35]. Still shorter Ag-Pd distances have only been observed in [AgPd 2 (l-Cl) (l-PPh 2 )(l-dppe){Mn(CO) 4 } 2 ] (2.7259(6) and 2.8014(6) Å ) [36].…”

“…[9,14,30,[63][64][65] Complex 7 shows a peculiar behaviour in solution that is explained with the proposal shown in Scheme 4. For the Pt-Pt species 6, the stable form in solution is that with a bridging (and dynamic) AgPPh 3 moiety, which is equilibrium b (Scheme 5) shifted to the right.…”

Keywords: Metal-metal interactions / P ligands / Palladium / Platinum / Structure elucidationThe reactions of [Ag(OClO 3 )(PPh 3 )] F 5 )(tht)] (M = Pt, Pd; hq = 8-hydroxyquinolinate, bq = benzoquinolinate, pic = picolinate, tht = tetrahydrothiophene) afford the corresponding neutral adducts [(C 6 F 5 ) 2 Pt-(μ-PPh 2 ) 2 (μ-AgPPh 3 )M(bq)] (M = Pt, 1; Pd, 2), [(C 6 F 5 ) 2 Pt(μ-PPh 2 ) 2 (μ-AgPPh 3 )M(hq)] (M = Pt, 3; Pd, 4) [(C 6 F 5 ) 2 Pt(μ-PPh 2 ) 2 -(μ-AgPPh 3 )Pt(C 6 F 5 )(tht)] (5) and [(C 6 F 5 ) 2 Pt(μ-PPh 2 ) 2 M(pic-AgPPh 3 )] (M = Pt, 6; Pd, 7) as yellow solids. The XRD structures of 1-5, in which a [AgPPh 3 ] + moiety bridges the metal Eur. 1679centres, were confirmed in solution at low temperature. At room temperature, a dynamic process for the [AgPPh 3 ] + moiety, which passes from the top to the bottom part of the molecules 1-5, was ascertained. For 6 and 7, the XRD analyses revealed structures in which the [AgPPh 3 ] + moiety is linked to the picolinate oxygen atom bonded to the M centre; however, although such a structure was confirmed in solution for the Pt-Pd species 7, the stable form of the Pt-Pt species 6 in solution is that with the [AgPPh 3 ] + moiety bridging the metal centres.www.eurjic.org FULL PAPER Scheme 1. num(III) (Scheme 1, type F) and the consequent formation of metallic silver. [38,[42][43][44] Finally, an example has been reported in which the L-LЈ ligand of [Ag 2 {Pt 2 (μ-PPh 2 ) 2 -(C 6 F 5 ) 2 (acac)} 2 ] (acac = acetylacetonate) acts as donor towards the silver atom (Scheme 1, type G and H). [36] In our experience, the results obtained so far in these types of reactions indicate that it is impossible to predict the behaviour of a particular complex towards Ag I .Recently, we have reported the reactions of I 2 with [NBu 4 ][(C 6 F 5 ) 2 Pt II (μ-PPh 2 ) 2 M II (C ∧ N)] [45] and [NBu 4 ]-[(C 6 F 5 ) 2 Pt II (μ-PPh 2 ) 2 M II (O ∧ N)] [46] [M = Pt, Pd; C ∧ N = benzoquinolinate (bq); O ∧ N = 8-hydroxyquinolinate (hq), picolinate (pic)], which contain dinuclear asymmetric anionic complexes and a chelate ligand. In all cases, the addition of molecular I 2 to the complexes resulted in oxidation of the metal centre and the formation of M II -M IV intermediates, which evolved through a PPh 2 /C ∧ N or PPh 2 / O ∧ N reductive coupling with the formation of new M II -M II compounds.In this paper, we report the results obtained in the reactions of anionic complexes of platinum(II) and palladium(II) containing benzoquinolinate, 8-hydroxyquinolinate, tetrahydrothiophene (tht) and picolinate ligands with [AgPPh 3 (OClO 3 )]; these reactions were performed to establish the type of complex (A-H, Scheme 1) obtained when the different dinuclear phosphanido platinum or palladium fragments are reacted with Ag I salts.
