Coordination compounds of lanthanides with polydentate phosphine oxide ligands


  Polymeric coordination compounds are now intensively studied because of their potential
application in many areas such as hydrogen and methane storage, gas separation, catalysis,
luminescence, drug storage and transport etc. Coordination chemistry of lanthanides slightly
differs from that of the d-block elements owing to their larger ionic radii and lower
electronegativity. This allows lanthanides to create compounds with higher coordination numbers
when they react with ligands containing hard donor atoms.

  Our research aims at synthesis of coordination compounds of lanthanides with ligands that have
two Ph[2]P(O)- groups or one Ph[2]P(O)- and one COOH group. These compounds adopt various
structures from simple molecular complexes to three-dimensional coordination polymers.
