Coinage metals, electronic configuration

The Group 11 metals, copper, silver, and gold, are called the coinage metals and have valence electron configurations of (n - l)a °ra... [Pg.207]

The iron carbonyl vertices of these coinage metal iron carbonyl clusters (Figure 14) are always Fe(CO>4 units, which are of two types, namely, divalent (degree 2) Fe(CO)4 vertices forming two Fe-M bonds and trivalent (degree 3) Fe(CO>4 vertices forming three Fe-M bonds. In order for the iron atoms in these Fe(CO>4 vertices to have the favored 18-electron noble gas configuration, the divalent Fe(CO)4 vertices... [Pg.395]

From the form of the mass-velocity and Darwin operators, it is clear that the largest contributions to the direct scalar relativistic effect come from s electrons. Consequently, sa bonds should be strengthened by relativity. The coinage metals have valence configurations and we would expect compounds of these elements to exhibit such effects in their bonding properties. Table 22.3 shows the bond lengths, harmonic... [Pg.457]
