Three-dimensional networks of lanthanide 1,2,4-triazolates: 3∞[Yb(Tz)3] and 3∞[Eu2(Tz)5(TzH)2], the first 4f networks with complete nitrogen coordination

Abstract

The solvent-free melt reaction of Eu and Yb with the N-heterocycle 1,2,4-triazole, gives the first three-dimensional networks of the lanthanides with complete nitrogen coordination spheres, further being the first unsubstituted triazolates of the lanthanides and exhibiting different valences.
