Complexes with 6-Ligands

In addition to the oxide carboxylates, beryllium forms numerous chelating and bridged complexes with ligands such as the oxalate ion C204 , alkoxides, /9-diketonates and 1,3-diketonates. These almost invariably feature 4-coordinate Be... [Pg.122]

Class-b acceptors on the other hand are less electropositive, have relatively full d orbitals, and form their most stable complexes with ligands which, in addition to possessing lone-pairs of electrons, have empty n orbitals available to accommodate some charge from the d orbitals of the metal. The order of stability will now be the reverse of that for class-a acceptors, the increasing accessibility of empty d orbitals in the heavier halide ions for instance, favouring an increase in stability of the complexes in the sequence... [Pg.910]

It is possible to observe spin-allowed, d d bands in the visible region of the. spectra of low-spin cobalt(lll) complexes because of the small value of 0Dq, (A), which is required to induce spin-pairing in the cobalt(lll) ion. This means that the low-spin configuration occurs in complexes with ligands which do not cause the low -energy charge transfer bands whieh so often dominate the spectra of low-spin complexes. [Pg.1128]

Nevertheless, Cu can be stabilized either in compounds of very low solubility or by complexing with ligands having 7r-acceptor character. Its solutions in MeCN are stable and electrochemical oxidation of the metal in this solvent provides a convenient preparative route. The usual stereochemistry is tetrahedral as in... [Pg.1194]

Although Zn2+ is essential to human nutrition, compounds of the two elements below zinc in the periodic table. Cd and Fig. are extremely toxic. This reflects the fact that Cd2+ and Flg2+, in contrast to Zn2+, form very stable complexes with ligands containing sulfur atoms. As a result, these two cations react with and thereby deactivate enzymes containing —SH groups. [Pg.550]

Removing electrons from a metal atom always generates vacant valence orbitals. As described in Chapter 20, many transition metal cations form complexes with ligands in aqueous solution, hi these complexes, the ligands act as Lewis bases, donating pairs of electrons to form metal-ligand bonds. The metal cation accepts these electrons, so it acts as a Lewis acid. Metal cations from the p block also act as Lewis acids. For example, Pb ((2 g) forms a Lewis acid-base adduct with four CN anions, each of which donates a pair of electrons Pb ((2 ( ) + 4 CN ((2 q) -> [Pb (CN)4] (a g)... [Pg.1503]

The use of y-ray induced radical pol5unerization proved to be a successful alternative for the radical co-polymer-ization of metal complexes with ligands containing acrylic C—C double bonds [100-102,129,130]. In particular, the palladium(II) complex cw-[PdCl2(ICPA)2] (1, Scheme 4) was co-polymerized in DMF solution with DMA and MBAA (cross-linker, 4% mol), with no degradation of the metal center [100,101]. [Pg.216]

The K-edge spectra of [Ni(287)2]2 and [Ni(cdt)2]2 are remarkably similar to each other and to those of natural hydrogenases.196 Some complexes with ligand (289) (R = NMe2, R = H, Me, NMe2) have been characterized using electronic and near infrared spectroscopy.823 Complex [Ni(289)2]2 served to study phase transformation behavior by microscopy and DSC.824... [Pg.325]

Complexes with the bdt ligand are less recognized, but some type (388) complexes with ligands derived from bdt have shown interesting properties. (NEt4)A[Ni(S2C6I I3CI I3)2] (x = 2, 1) has been studied for its electrochemical and spectroscopic properties.1059... [Pg.340]

NiL2] complexes with ligands (529) and (530) have been synthesized using electrochemical methods. In the presence of further donors they form octahedral complexes.1385 Ligand (531)... [Pg.369]

Complexes with ligands bearing alkylpyridine pendant arms attached to an ethylenediamine framework were prepared, and their spectral and redox properties were studied (238), (239), and (240) (r = 0.10).222... [Pg.784]
