Diastereomeric metallatetrahedron complexes of the type Re2(MPPh3)(M′PPh3)(µ-PCy2)(CO)7(–)-thiocamphanate (M = Ag, Au, M′ = Cu, Ag, Au): synthesis, structure and CD data

A mild and efficient rhenium-catalyzed transfer hydrogenation of terminal olefins using alcoholysis of amine–borane adducts as a reducing system

“…However, only in the case of trimethylamineeborane, the reaction was still incomplete after 3 days, presumably due to blockage of the rhenium center by the relatively strong trimethylamine ligand formed during the reaction course (entry 4). Low oxidation state rhenium complexes of trimethylamine are known with various ancillary ligand environments, which makes the existence of amine complexes of the type [ReBr 2 (NO)(NR 3 )(PTA) 2 ] quite plausible [46,47]. Ammonia stemming from ammoniaeborane could lead also to a relatively strong ammonia complex.…”

Gold–Heterometal Interactions and Bonds

“…Most of them contain tetrahedral AuRe 3 [199,200] or AuRe 2 M (M¼ Cu, Ag) [194,201,202], Au 2 Mn 2 [180], Au 2 Re 2 [190,194,[202][203][204][205] and Au 3 Re [188] skeletons …”

“…The shortest Au-Cu distances within the cluster cation are 3.216(4) and 3.376(4) Å, which indicates weak Au III -Cu I interactions. Trimetallic clusters with tetrahedral AuRe 2 Cu [201,202] or capped-trigonal bipyramidal AuRu 4 Cu [345,346] skeletons have also been reported. Examples are [(Ph 3 P) Au][(Ph 3 P)Cu]Re 2 (m-PCy 2 )(CO) 7 (C:CPh) 167 [Au-Cu 2.644(2) Å] [201] or (m-dppe) AuRu 4 Cu(m 3 -H) 2 (CO) 12 231 [Au-Cu 2.614(2) Å] [345].…”

The influence of alkane spacer of bis(diphenylphosphino)alkanes on the nuclearity of silver(I): Syntheses and structures of P,P′-bridged clusters and coordination polymers involving dithiophosphates

“…The study of silver-silver short contact in complexes, less than twice of van der Waal's radii of silver atom (3.40 Å), has invited attention of several research groups in the recent years [2][3][4][5][6][7][8], as such interaction has led to generate interesting electrical conducting properties [9,10]. The sulfur donor ligands have played an important role in the formation of such interactions due to their ability to bring two or more metals in close contact in view of angular flexibility at sulfur donor atoms [2][3][4][5][6][7][8][9][10][11][12][13][14][15][16].…”

“…The sulfur donor ligands have played an important role in the formation of such interactions due to their ability to bring two or more metals in close contact in view of angular flexibility at sulfur donor atoms [2][3][4][5][6][7][8][9][10][11][12][13][14][15][16]. Furthermore, silver-sulfur interactions are more covalent in nature due to the soft-soft acid-base interactions, and such interactions enhance the argentophilic character of silver atoms.…”
