Before continuing, some words of clarification are due. Although there exist a limited number of polynuclear lanthanide complexes whose component metal ions are shown to participate in intramolecular energy transfer (Thompson et al., 2001), for most such complexes, there is no apparent metal-metal bonding, nor are there any significant interactions mediated by the commonly observed bridging ligands, a consequence of... 

Alternatively, hydrolysis of presumably not so soluble lanthanide carboxylate complexes may be possible by carrying out the hydrolysis under hydrothermal conditions. It appears that such conditions (high temperature and high pressure) are particularly conducive to the formation of polynuclear lanthanide complexes, often with unpredictable but nevertheless interesting structure. Under ambient pressure, analogous synthesis generally produces complexes with carboxylate coordination only and without any involvement of hydroxo groups.

The synthesis, structures, and luminescence properties of polynuclear lanthanide complexes and lanthanide coordination polymers, which are formed from multidentate oxygen and nitrogen-containing Schiff-base ligands, are described in this chapter. 

Polynuclear lanthanide complexes and lanthanide coordination polymers with distinct magnetic and luminescent properties are currently of interest for the use in applications involving the fabrication of novel materials and as probes in biological systems. However, compared to polynuclear complexes of the d-block transition metals, the design and...

While the majority of polynuclear lanthanide complexes and coordination polymers have been synthesized by the use of rigid ligands, such as multicarboxylic acids and carboxyphenyl porphyrin, relatively few studies involving more flexible ligands have been reported. However, the skeletal adapfabiUfy of flexible ligands enables them to form many different molecular systems and extended network... 

Two kinds of salen-type Schiff-base ligands, conjugated and flexible, have been used in the synthesis of polynuclear lanthanide complexes and lanthanide coordination polymers Lanthanides Coordination Chemistry, Rare Earth Metal Cluster Complexes. The stoichiometry and structures of these complexes are dependent on the Schiff-base... 

In the first part of this chapter, we have tried to demonstrate that the lanthanide ions can give rise to the formation of a variety of mononuclear supramolecular systems that can be employed for sensing and imaging, and in the formation of novel self-assembly structures that can be further exploited for use in materials-based systems. The next part of this chapter demonstrates that such supramolecular structures can be expanded to polynuclear lanthanide complexes and self-assemblies.
