Bridging ligands coordination compounds

An alternative for such purposes is a Copper(II) chlorate(VII) coordination polymer with 4-amino-1,2,4-triazole as bridging ligand. This compound has a ID chain structure in which Cu + ions are linked by triple triazole nitrogen bridges. It is a high explosive with a performance close to that of lead azide, but it... 

The CK" ion can act either as a monodentate or bidentate ligand. Because of the similarity of electron density at C and N it is not usually possible to decide from X-ray data whether C or N is the donor atom in monodentate complexes, but in those cases where the matter has been established by neutron diffraction C is always found to be the donor atom (as with CO). Very frequently CK acts as a bridging ligand - CN- as in AgCN, and AuCN (both of which are infinite linear chain polymers), and in Prussian-blue type compounds (p. 1094). The same tendency for a coordinated M CN group to form a further donor-aceeptor bond using the lone-pair of electrons on the N atom is illustrated by the mononuclear BF3 complexes... 

Furan is typically tiVC) coordinated in a series of organometallic compounds. However, it is its ti (C=C) coordination that opened a perspective toward a broad series of derivatized furans. It can be a bridging ligand forming (C=C)... 

Figure 86 Compound containing a full M2L4 helical cage that has each square-planar palladium atom coordinated to the four bridging ligands and within which resides a well-ordered PF6 ion.
