چکیده
In the title complex, [CoPd(2)(C(3)H(5))(2)(C(8)H(11))Cl(2)(C(40)H(30)P(2))]·CH(2)Cl(2), the Co(I) atom is sandwiched between the cyclo-penta-dienyl and cyclo-butadiene rings. The two diphenyl-phosphine substituents of the cyclo-butadiene ring are situated opposite to each other and bind two Pd(II) atoms, which are additionally coordinated by a chloride ion and the three C atoms of an allyl ligand, forming a distorted planar coordination environment. The Cl atoms of the dichloro-methane solvent mol-ecule (equal occupancies) and one C atom and its attached H atom of each of the allyl ligands (occupancies 0.55:0.45) are disordered.

The title linear trinuclear copper(II) complex, [Cu(3)(C(17)H(20)N(2)O(2))(2)Cl(2)], was obtained from N,N'-bis-(2-hydroxy-benz-yl)-1,3-propane-diamine and CuCl(2). The overall charge of the three Cu(2+) ions is balanced by four deprotonated phenol groups and two Cl(-) ligands. The complex is centrosymmetric with the central Cu(2+) occupying a special position (). This Cu(2+) ion is coordinated...

The title compound, [Rh2Br2(C8H12)2(C17H32N4)], was obtained by the reaction of 3,3'-(propane-1,3-di-yl)bis-(1-isopropyl-3,4,5,6-tetra-hydro-pyrimidin-1-ium) bromide and [{Rh(cod)Cl}2] (cod is cyclo-octa-1,5-diene) in tetra-hydro-furan. The two Rh(I) atoms each have a distorted square-planar coordination environment, defined by a bidentate cod ligand, a bromide anion and one C atom of the bridg...

The asymmetric unit of the title compound, [Co(NCS)(2)(C(13)H(14)N(2))(CH(3)OH)(2)], consists of one cobalt(II) cation located on a center of inversion, one half of a 1,3-bis-(pyridin-4-yl)propane ligand located on a twofold rotation axis, as well as one thio-cyanate anion and one methanol mol-ecule in general positions. The cobalt(II) cation is coordinated by two terminal N-bonded thio-cyanate...

In the title coordination polymer, [Ag(2)(NCS)(2)(C(27)H(26)P(2))(2)](n), two centrosymmetrically related Ag(+) cations are linked by two thio-cyanate anions into binuclear eight-membered macrocycles. The Ag⋯Ag separation within the macrocycle is 5.4400 (6) Å. The distorted tetra-hedral coordination about each metal atom is completed by the P atoms of two bridging 1,3-bis-(diphenyl-phosphan-yl)...
متن کاملCobalt-catalysed asymmetric hydrovinylation of 1,3-dienes† †Electronic supplementary information (ESI) available. See DOI: 10.1039/c5sc00929d
In the presence of bidentate 1,n-bis-diphenylphosphinoalkane-CoCl2 complexes {Cl2Co[P~P]} and Me3Al or methylaluminoxane, acyclic (E)-1,3-dienes react with ethylene (1 atmosphere) to give excellent yields of hydrovinylation products. The regioselectivity (1,4- or 1,2-addition) and the alkene configuration (E- or Z-) of the resulting product depend on the nature of the ligand and temperature at ...
