A mixed-valence lanthanide metal-organic framework, templated by 2,2′-bipyridine formed in situ reaction: Synthesis, structure, and luminescent properties

A novel lanthanide metal-organic framework, {(bpy)(0.5)[Dy-3(ip)(4)(phen)(4)(H2O)]center dot 2H(2)O}(n) has been synthesized via a hydrothermal method. Single-crystal X-ray analysis reveals that the center ions are mixed-valence Dy (II, III) and that trans-2,2'-bipyridine was formed in situ from 1,10-phenanthroline under hydrothermal conditions in the presence of Dy(III) ions.
