Trimetallic Au24-xAgxPd and tetrametallic Au24-x-yAgxCuyPd clusters were synthesized by the subsequential metal exchange reactions of dodecanethiolate-protected Au24Pd clusters. EXAFS measurements revealed that Pd, Ag, and Cu dopants preferentially occupy the center and edge sites of the core, and staple sites, respectively. Spectroscopic and theoretical studies demonstrated that the synergisti...

A thorough examination of the disassembly of bimetallic triple-stranded lanthanide helicates [Ln2(Li)3]6+ (stoichiometry S = m/n = 2/3 = 0.67, global complexity GC = m + n = 2 + 3 = 5) in excess of metals shows the competitive formation of standard linear bimetallic complexes [Ln2(Li)2]6+ (S= 1.0, GC = 4), and circular trimetallic single-stranded helicates [Ln3(Li)3]9+ (S= 1.0, GC = 6).

This work introduces the new trimetallic complex CoPd2(HBPDC)2Cl4·(H2O)4(H2BPDC = 2,2'-bipyridine-4,4'-dicarboxylic acid) as a highly efficient and more cost-effective catalyst for a Suzuki-Miyaura reaction proceeding in water, without additives and under aerobic conditions. Catalytic studies revealed a synergistic Co-Pd cooperativity, fostered by ligation through H2BPDC, and accounting for the...

The first trimetallic dysprosocenium single-molecule magnet is described. This material signposts a polycationic dysprosium metallocene SMM with properties that could surpass those of leading systems.

Multidentate tripodal ligands, N(CH2-m-C6H4-CH2tacn)3 (L1) and N(CH2-o-C6H4-CH2N(CH2py)2)3 (L2), have been devised for assembling high-nuclearity metal clusters. By using the same tripodal platform with different ligand appendages, either triazacyclononanes or dipicolylamines, and functionalizing either the ortho or the meta positions on the tris(xylyl) linker arms, discrete trimetal phosphate ...

Nanoparticles are materials whose size is less than 100 nm. Because of their distinctive physical and chemical characteristics, nanoparticles have drawn considerable interest in a variety fields. Biosynthesis green environmentally friendly technology, which requires fewer reagents, precursors, catalysts. There various types nanomaterials, out trimetallic receiving recent years. Trimetallic poss...

Expanding the versatility of well defined clusters is a major concern in the design of building blocks towards functional nanostructures. W@Au12 is a prototypical binary bare superatomic cluster involving an icosahedral symmetry, which has been discussed in the literature, precluding the proposal of several endohedral d-block and f-block element structures within a golden cage. Here we pursue t...

A series of gold(III) and palladium(II) heterometallic complexes with new iminophosphorane ligands derived from ferrocenylphosphanes [{Cp-P(Ph2)═N-Ph}2Fe] (1), [{Cp-P(Ph2)═N-CH2-2-NC5H4}2Fe] (2), and [{Cp-P(Ph2)═N-CH2-2-NC5H4}Fe(Cp)] (3) have been synthesized and structurally characterized. Ligands 2 and 3 afford stable coordination complexes [AuCl2(3)]ClO4, [{AuCl2}2(2)](ClO4)2, [PdCl2(3)], an...
