Lanthanide contraction effect and white-emitting luminescence in a series of metal-organic frameworks based on 2,5-pyrazinedicarboxylic acid.

ABSTRACT: A series of lanthanide and yttrium MOFs of two structural types [M₂(H₂O)₂(nmp)₂(pzc)₃] (1M) and [M₂(H₂O)₄(pzc)₃]·NMP·5H₂O (2M) (where M - lanthanide or yttrium cation, nmp - N-methyl-2-pyrrolidone, pzc^2- - 2,5-pyrazinedicarboxylate) was synthesized and characterized by single crystal and powder X-ray diffraction crystallography, TG, elemental analyses and IR-spectroscopy. The effect of lanthanide contraction has led to the fact that lanthanides at the beginning of the series (from lanthanum to gadolinium) have a structure different from the structure of lanthanides at the end of the series and yttrium (from terbium and beyond). According to PXRD patterns of the ob
