Wietzke, R., Mazzanti, M., Latour, J.M., Pecaut, J., Cordier, P.Y., Madic, C. 1998. Lanthanide(III) complexes of tripodal N-donor ligands Structural models for the species involved in solvent extraction of actinides(III). Inorganic Chemistry 37(26) 6690-6697. [Pg.178]

It is often difficult to represent inorganic compounds with the usual structure models because these structures are based on complex crystals space groups), aggregates, or metal lattices. Therefore, these compounds are represented by individual polyhedral coordination of the ligands such as the octahedron or tetrahedron Figure 2-124d). [Pg.135]

In order to construct new types of binding and activating models of dioxygen molecules, Jitsukawa, Masuda and their co-workers have synthesized a novel group of tripodal tetradentate ligands and successfully utilized them in the formation of mononuclear copper(II) complexes with novel structural features (complexes (473)-(488)).395-403 This group of ligands has four... [Pg.835]

Using 1,4,8,11-tetraazacyclotetradecane, the structure of complex (800) (distorted trigonal planar Cu-Cu 6.739 A) was determined. Reactivity with 02 was investigated to demonstrate the formation of trans-l,2-peroxo species.585 As part of their work with copper(I) complexes with 02, the structure of a dicopper(I) complex ((801) distorted tetrahedral 7.04 A), supported by macrocyclic ligand environment, was reported by Comba and co-workers. Tolman and co-workers structurally characterized a three-coordinate copper(I)-phenoxide complex (802) (planar T-shaped) that models the reduced form of GO.587 The copper(I) analogue [Cu(L)][CF3-SO3]-0.43MeOI I (803) of a copper(II) complex (534) was also reported to demonstrate the role of ligand framework conformability in CV /Cu1 redox potentials.434 Wilson and co-workers... [Pg.897]

The zinc acetate complex of tris(3-/-butyl-5-methylpyrazol-l-yl)borate was prepared as a structural model for carbonic anhydrase and comparison with the enzyme active site structures confirmed that the complexes are excellent structural models.239 A mononuclear zinc hydroxide complex can also be formed with the tris(pyrazolyl) borate ligand system as a structural model for carbonic anhydrase.240... [Pg.1164]

These spectroscopic data support a square-pyramidal structure in solution with the phosphines mutually trans disposed, the chloride and the carbonyl group occupying the basal sites, and the hydride ligand located at the apex. This structure fully agrees with that found in the solid state, by X-ray diffraction analysis for the related compound OsHCl(CO)(PCy3)218, and for ab initio DFT (Becke 3LYP) methods for the model complex OsHC1(CO)(PH3)2.19... [Pg.4]
