Gold II Complexes

Laguna, A. and Laguna, M. (1999) Coordination chemistry of gold(II) complexes. Coordination Chemistry Reviews, 193-195, 837-856. [Pg.38]

Porter, L.C. and Fackler, J.P. Jr (1986) Structure of the first example of an organometallic dinuclear gold(II) complex possessing bonds to oxygen. Acta CrystaUographica, 42, 1128-1131. [Pg.40]

Table 3.14 shows all the known dinuclear gold(II) complexes containing the AU2" core. As happened in gold(II) chemistry the most abundant are those containing a double bridge of the bis ylide CH2PPh2CH2. The first derivative [(C6F5)Au... [Pg.156]

The disproportionation reactions for dinuclear gold(II) complexes to give gold (III)/gold(I) derivatives are known and well represented. On the contrary only one... [Pg.158]

Since the most abundant gold(II) complexes belonging to the Au2 formulation have been discussed above, now we will refer to nudearity higher than two. This includes complexes with more than two gold atoms in the molecule or with other metals in their composition in addition to the gold centers (see Table 3.15). [Pg.159]

Mononuclear gold(II) complexes, consistent with a d9 configuration, must be paramagnetic (Meff=1.79 MB) and show a hyperfine four-line EPR signal, in accordance with the nuclear spin of 197Au (1 = 3/2). These two properties are evidence of a real gold(II) complex in addition to their stoichiometry. [Pg.1017]

As earlier mentioned, one of the reasons of the poor stability of gold(II) complexes is the unfavorable energy of the odd electron. The formation of a metal—metal bond in dinuclear gold(II) complexes giving diamagnetic species provides an extra stability. Thus, the number of... [Pg.1018]

Another general procedure to prepare gold(II) complexes consists of substitution reactions on gold(II) derivatives. Halide ligands can be substituted by neutral donor ligands2025-2032 such as... [Pg.1021]

X = Cl, Br, I, SCN Figure 19 Some examples of asymmetric bridged gold (II) complexes. [Pg.1023]

Other heteropolynuclear gold(II) complex that can be obtained by replacement of halide groups in bis(ylide)gold(II) species by other anionic nucleophilic metal complex is the tin derivative [Au2 Sn[N(p-Tol)SiMe2]3SiMe 2 M-(CH2)2PPh2 2] (350).2041... [Pg.1024]
