Metal Cluster Terminated “Molecular Wires”

Diruthenium compounds of thiol capped oligo(phenyleneethynyl) ligand: Synthesis and characterization

“…It has been noted that figures of merit of materials may be improved over pure organic oligomers when metal centers are incorporated into conjugated oligomers either in the main chain or as the side chain pendants [8]. Transition metal compounds with ligand containing OPEn fragment (OPEn = (C"CC 6 H 4 ) n , n P 2) have become increasingly common in recent years, and examples include the a,x-ferrocenyl-OPEn-thioether series [9], an Os 3 cluster with a r-S-S(C 6 H 4 C"C) 2 Ph ligand [10], and various Ru(II) and Au(I) complexes coordinated by OPEn ligands in both r-and g 2 modes [11]. Our laboratory is interested in developing molecular wires based on linear metal-alkynyl species with a focus on diruthenium compounds supported by N,N 0 -bidentate ligands [12,13].…”

Gold–Heterometal Interactions and Bonds

“…Similar (AuM 2 )M cores were found for the Au-Ru [261][262][263][264][265][266][267][268][269][270][271][272][273][274][275][276][277][278] and Au-Os [276,[279][280][281][282][283][284][285][286][287][288][289][290] [290]. Bis-cluster species in which two (AuRu 2 )Ru cores are connected through buta-1,3-diyne derivatives as bridging ligands have been described [290].…”

Alkynyl-Phosphine Substituted Fe2S2 Clusters: Synthesis, Structure and Spectroelectrochemical Characterization of a Cluster with a Class III Mixed-Valence [FeFe]3+ Core

“…Trimethylamine Noxide was freshly sublimed before use, [Fe 2 (µ-pdt)(CO) 6 ] [35] and compound 2 [33] were synthesised by minor variation to the procedures described in the literature, as detailed below. The precursor alkyne 1-ethynyl-4-(p-tolylethynyl)benzene was prepared as described elsewhere [58]. All other reagents were commercially available and used as received.…”
