In the title compound, [Cu(CH(3)CO(2))(2)(C(9)H(7)N(3))(H(2)O)](n), the Cu(II) ion is penta-coordinated in a square-pyramidal geometry. The N atoms of the two chelating symmetry-related 5-(pyridin-3-yl)pyrimidine ligands and the O atoms of the two monodentate acetate anions are nearly coplanar, with a mean deviation from the least-squares plane of 0.157 (2) Å and the Cu(II) ion is displaced by ...

In the title compound, [Zn(NO(3))(2)(C(7)H(9)NO)(2)], the Zn(II) atom, lying on a twofold rotation axis, is six-coordinated in a distorted octa-hedral geometry by two N atoms and two O atoms from two (2-amino-phen-yl)methanol ligands and two O atoms from two monodentate nitrate anions. Inter-molecular N-H⋯O, O-H⋯O and C-H⋯O hydrogen bonds stabilize the crystal structure.

In the title complex, [Co(C(15)H(9)N(2)O(6))(2)(H(2)O)(4)]·2H(2)O, the Co(II) ion is located on an inversion center and is coordinated by two monodentate 3-carb-oxy-5-[(4-carb-oxy-phen-yl)diazen-yl]benzo-ate ligands and four water mol-ecules in a distorted octa-hedral geometry. In the crystal, inter-molecular O-H⋯O hydrogen bonds link the mol-ecules into a three-dimensional supra-molecular netw...

In this chapter the results of kinetic studies of the rhodium-catalyzed asymmetric hydrogenation using monodentate phosphoramidite ligands are described. Together with the data obtained by a number of other techniques a mechanism for the Rhcatalyzed asymmetric hydrogenation with MonoPhosTM is proposed. The formation of the catalyst precursor results in a mixture of diastereomeric Rh-complexes w...

The title coordination polymer, {[Nd(2)(C(4)H(2)O(4))(3)(H(2)O)(4)]·3H(2)O}, was synthesized by the reaction of neodymium(III) nitrate hexa-hydrate with fumaric acid in a water-methanol (7:3) solution. The asymmetric unit comprises two Nd(3+) cations, three fumarate dianions (L(2-)), four aqua ligands and three uncoordinated water mol-ecules. The carboxyl-ate groups of the fumarate dianions exh...
