Main Group Parallels with Binary

4-6 MAIN GROUP PARALLELS WITH BINARY CARBONYL COMPLEXES [Pg.96]

Chemical similarities occur between main group and transition metal species that are electronically equivalent (i.e., species that require the same number of electrons to achieve a filled valence configuration).28 For example, a halogen atom, one electron short of a valence shell octet, may be considered electronically equivalent to Mn(CO)5, a 17-electron species one electron short of an 18-electron configuration. In this section we discuss briefly some parallels between main group atoms and ions and electronically equivalent binary carbonyl complexes. [Pg.96]

Much of the chemistry of main group and metal carbonyl species can be rationalized from the way in which these species can achieve closed-shell (octet or 18-electron) configurations. These methods of achieving more stable configurations are illustrated for the following electronically equivalent species. [Pg.96]

HCo(CO)4are strong acids in aqueous solution. Both types of anions form precipitates with heavy metal ions such as Ag+ in aqueous solution. The parallels between seven-electron halogen atoms and 17-electron binary carbonyl species are sufficiently strong to justify applying the label pseudohalogen to these carbonyls.29 [Pg.97]

Similarly, six-electron main group species show chemical similarities with 16-electron organometallic species. As for the halogens and 17-electron organo-metallic complexes, many of these similarities can be accounted for on the basis of ways in which the species can acquire or share electrons to achieve filled-shell configurations. Some similarities between sulfur and the electronically equivalent Fe(CO)4 are listed in Table 4-6. [Pg.97]
