Synthesis, characterization, and gas-phase fragmentation of rhenium-carbonyl complexes bearing imidazol(in)ium-2-dithiocarboxylate ligands.
Five complexes with the generic formula [ReBr(CO)3(κ2-S,S'-S2C·NHC)] were obtained by reacting [ReBr(CO)5] with a set of representative imidazol(in)ium-2-dithiocarboxylate zwitterions. These ligands are the adducts of N-heterocyclic carbenes (NHCs) and carbon disulfide. The monometallic Re(i) compounds were further coupled with Na[Re(CO)5] to afford bimetallic Re(0) species. Depending on the ex...
متن کاملStudies of the Structures and Bonding of Gold-Bridged Dirhenium Carbonyl Cluster Complexes
The compounds Re2(CO)8(μ-AuPPh3)2, 1, a dimer of Re(CO)4(μ-AuPPh3), and ax,ax-Re2(CO)8(PPh3)2 were obtained from UV−vis radiationinduced decarbonylation of the compound Re(CO)5[Au(PPh3)]. Compound 1 contains two rhenium atoms bridged by two AuPPh3 groups. The complex has 32 valence electrons and is formally unsaturated by the amount of two electrons. The Re−Re bond distance in 1 is unusually sh...
متن کاملMorpholine–4-nitrophenol (1/2)
In the title adduct, 2C6H5NO3·C4H9NO, the morpholine ring adopts a chair conformation. The dihedral angle between the two nitro-phenol rings is 69.47 (9)°. The nitro groups attached to the benzene rings make dihedral angles of 3.37 (16) and 3.14 (13)° in the two mol-ecules of nitro-phenol. The crystal structure is stabilized by N-H⋯O, O-H⋯N and O-H⋯O hydrogen bonds and further consolidated by C...
متن کاملHighly emissive platinum(II) complexes bearing carbene and cyclometalated ligands.
A series of heteroleptic platinum(II) complexes (1a-3a and 1b-3b) bearing a dicarbene ligand and a cyclometalated bidentate ligand have been prepared. Two of the complexes (1a and 3a) were characterized by X-ray diffraction analyses, confirming the square-planar structures. Detailed spectroscopic properties of the complexes have been studied, and two complexes, 3a and 3b bearing a carbene chela...
متن کاملTowards new organometallic wires: tetraruthenium complexes bridged by phenylenevinylene and vinylpyridine ligands.
The tetranuclear complexes [{(PiPr(3))(2)(CO)ClRu(mu-CH=CHpy)Ru Cl(CO)(PPh(3))(2)}(2)(mu-CH=CH-C(6)H(4)- CH=CH-1,4)] (3 a) and [{(PiPr(3))(2)(CO)ClRu(mu-CH=CHpy)RuCl(CO)(PPh(3))(2)}(2)(mu-CH=CH-C(6)H(4)-CH=CH-1,3)] (3b), which contain vinylpyridine ligands that connect peripheral Ru(PiPr(3))(2)(CO)Cl units to a central divinylphenylene-bridged diruthenium core, have been prepared and investigat...
