Abstract

Lanthanide containing materials are of interest to the field of crystal engineering because of their unique properties and distinct structure types. In this contribution, a new samarium—sodium heterometallic coordination polymer with the chemical formula [SmNa(C8H7O3)4]·solvent (Sm-1) was synthesized and crystallized via slow evaporation from a mixture of ethanol and acetonitrile. The compound features alternating Sm(III) and Na(I) ions, which are linked by o-vanillin ligands to form a one-dimensional chain-like coordination polymer. The chains propagate along the [001] direction and are stabilized by van der Waal interactions. The structural, vibrational, and optical properties are reported.
