Chlorido bridges

In names of coordination compounds, the ligand names precede the name of the central atom and are cited in alphabetical order. For each ligand type, bridging ligands are cited immediately before terminal ligands of the same kind, if any, e.g. di-p-chlorido-... 

In bridged dinuclear species, bridging ligands are indicated by the Greek letter p, placed before the ligand name and separated from it by a hyphen. The whole term, e.g. p-chlorido , is separated from the rest of the name by hyphens. If the bridging ligand occurs more than once, multiplicative prefixes are employed (see also Sections IR-9.1.2.10 and IR-9.2.5.2). 

The ability of chlorido ligands to bridge between two metal centres allows the formation of dinuclear species... 

Heating a solution of C0CI2 in THE at reflux produces the dark blue [Co4Cl2(p-Cl)6(THF)6] in which bridging chlorido ligands support the tetranuclear framework (Fig. 21.27b). 

CdCl( i2-N,0,0 -gly)(DABT)]n (DABT = 2,2 -diamino-4,4 -bis-l,3-thiazole). In this compound, each cadmium(II) is coordinated by a chlorido ion, a molecule from the diamine-bithiazole ligand and by two glycinate ions (one O-monodentate and the other N,0-bidentate). Consequently, the glycinate anions act as bridges between neighbouring cadmiums and form zig-zag chains [51].
