Reaction of deprotonated 2,5-bis(2'-pyridyl)pyrrole (HPDPH) with AgOTf (where OTf(-) = triflato) in THF readily yields a yellow triangular Ag3 complex [(PDPH)Ag]3 (1), of which the av. AgAg distance is 2.902 Å. A mixture of HPDPH and AgOTf reacts with PPh3 to afford a linear Ag3 complex [Ag{(PDPH)Ag(PPh3)}2](OTf) (2·OTf), whereas it reacts with diethyl phosphite in the presence of Li[N(SiMe3)2]...

The newly synthesized ligand, dihydro OO'bis(salicylidene) 2,2' aminobenzothiazolyl borate (2), was derived from the reaction of Schiff base of 2-aminobenzothiazole and salicylaldehyde with KBH(4). Cu(II) (3) and Zn(II) (4) complexes of (2) were synthesized and further metallated with dimethyltindichloride to yield heterobimetallic complexes (5) and (6). All complexes have been thoroughly chara...

The phenoxyimine cationic complex [L1Y(CH2SiMe2Ph)(THF)3][BArF] (L1 = (3-tBu)-(O)–C6H3–CH?N-(2,6-iPr-C6H3)) was prepared starting from the homoleptic [Y(CH2SiMe2Ph)3(THF)2] yttrium and ligand HL1 subsequent cationization by anilinium borate salt. resulting characterized different techniques such as elemental analysis, NMR (1H, 13C, 89Y), more specifically 1H-coupled 89Y INEPT. reactivity of tow...

The solvothermal reaction of [tris-(4-carboxylphenyl)phosphineoxide] (H3TPO) with UO2(NO3)2·6H2O in DMF affords a uranium-based chiral, microporous, metal-organic framework compound [(CH3)2NH2][UO2(TPO)]·4DMF·12.5H2O (SCU-3) that exhibits the highest void volume (68.8%) and second-harmonic generation (SHG) efficiency (1.54 KDP) for an actinide compound reported to date. The combination of large...

A unique cooperative H2 activation reaction by heterobimetallic (NHC)M'-MCp(CO)2 complexes (NHC = N-heterocyclic carbene, M' = Cu or Ag, M = Fe or Ru) has been leveraged to develop a catalytic alkyne semi-hydrogenation transformation. The optimal Ag-Ru catalyst gives high selectivity for converting alkynes to E-alkenes, a rare selectivity mode for reduction reactions with H2. The transformation...

A heterobimetallic catalyst, {Ti--Cr}, consisting of a constrained-geometry titanium olefin polymerization center (CGC(Et)Ti) covalently linked to a chromium bis(thioether)amine ethylene trimerization center (SNSCr) was synthesized and fully characterized. In ethylene homopolymerizations it affords linear low-density polyethylene with molecular weights as high as 460 kg·mol(-1) and exclusively ...
