In the title compound, [Co(C(7)H(3)Cl(2)O(2))(2)(C(10)H(8)N(2))(CH(3)OH)(2)](n), the Co(II) ion lies on a twofold rotation axis and is in a slightly distorted octa-hedral CdO(4)N(2) environment, formed by two O atoms from monodentate dichloro-benzoate ligands, two O atoms from methanol ligands, and two N atoms from trans-related 4,4'-bipyridine ligands. The bipyridine ligands also lies on a two...

A library of 20 monodentate phosphoramidite ligands has been prepared and applied in rhodium-catalyzed asymmetric hydrogenation. This resulted in the identification of two ligands, PipPhos and MorfPhos, that afford excellent and in several cases unprecedented enantioselectivities in the hydrogenation of N-acyldehydroamino acid esters, dimethyl itaconate, acyclic N-acylenamides, and cyclic N-acy...

[reaction: see text] Using a combination of chiral monodentate phosphoramidite ligands in the rhodium-catalyzed conjugate addition of boronic acids to three different substrates, we have shown for the first time that the ligand combination approach is applicable for C-C bond formation. Chiral catalysts based on hetero-combinations of ligands are found to be more effective than the homo-combinat...

In the crystal structure of the title complex, poly[[diazidomanganese(II)]-di-1,2-bis(imidazol-1-yl)ethaneN:N 0 ], [Mn(N3)2(C8H10N4)2]n or [Mn(N3)2(bim)2]n, where bim is 1,2-bis(imidazol-1-yl)ethane, each Mn atom is six-coordinated in a distorted octahedral coordination environment to four N atoms from four bim ligands and two N atoms from two azide ligands. The Mn atoms, which lie on inversion...

The molecule of the title compound, [Cu(2)(C(9)H(9)O(2))(4)(C(9)H(10)O(2))(2)], lies on a center of inversion. It consists of four bridging ethyl-benzoate ligands, forming a cage around two Cu atoms in a syn-syn configuration, and two monodentate ethyl-benzoic acid ligands bonded apically to the square-planar Cu atoms. The Cu⋯Cu distance is 2.6047 (5) Å.

The title compound, [Cd(C(8)H(4)O(5))(H(2)O)(3)](n), a one-dimensional chain complex of 5-hy-droxy-isophthalate with Cd(II), was prepared by a hydro-thermal reaction. The Cd(II) ion is coordinated by three water O atoms and three carboxyl-ate O atoms of two different 5-hy-droxy-isophthalate ligands, which act as bidentate and monodentate ligands. The crystal structure is stabilized by O-H⋯O hyd...

In the title triangulo-triruthenium compound, [Ru(3)(C(6)H(12)Cl(3)O(3)P)(CO)(11)], one equatorial carbonyl ligand is substituted by a monodentate phosphite ligand, leaving one equatorial and two axial carbonyl ligands on one Ru atom. The remaining two Ru atoms each carry two equatorial and two axial terminal carbonyl ligands. In the crystal structure, the mol-ecules are linked into a one-dimen...

Hydrogenation of levulinic acid (LA) to γ-valerolactone (GVL) was studied by using mono- and bidentate p-cymene ruthenium(ii) N-heterocyclic carbene (NHC) complexes as catalyst precursors. In water, all complexes were found to be reduced in situ to form ruthenium nanoparticles (RuNPs) with a high hydrogenation activity. In organic solvents, complexes with monodentate NHC ligands also formed nan...

A range of Ag(I) one- and two-dimensional coordination frameworks has been prepared and structurally characterized by using the multimodal ligand 3,6-di-pyrazin-2-yl-(1,2,4,5)-tetrazine, which offers both monodentate and chelating binding sites. It is demonstrated that multimodal ligands can be used to prepare coordination frameworks with novel and unusual topologies and to influence the precis...
