Two europium(III) coordination polymers (CPs), namely, poly[[diaquabis(μ4-1H-benzimidazole-5,6-dicarboxylato-κ6 N 3:O 5,O 5′:O 5,O 6:O 6′)(μ2-oxalato-κ4 O 1,O 2:O 1′,O 2′)dieuropium(III)] dihydrate], {[Eu2(C9H4N2O4)2(C2O4)(H2O)2]·2H2O} n (1), and poly[(μ3-1H-benzimidazol-3-ium-5,6-dicarboxylato-κ5 O 5:O 5′,O 6:O 6,O 6′)(μ3-sulfato-κ3 O:O′:O′′)europium(III)], [Eu(C9H5N2O4)(SO4)] n (2), have been synthesized via the hydrothermal method and structurally characterized. CP 1 shows a three-dimensional network, in which the oxalate ligand acts as a pillar, while CP 2 has a two-dimensional network based on a europium(III)–sulfate skeleton, further extended into a three-dimensional framework by hydrogen-bonding interactions. The structural diversity in the two compounds can be attributed to the different acidification abilities and geometries of the anionic ligands. The luminescence properties of 1 display the characteristic europium red emission with CIE chromaticity coordinates (2/3, 0.34). Interestingly, CP 2 shows the characteristic red emission with CIE chromaticity coordinates (0.60, 0.34) when excited at 280 nm and a near-white emission with CIE chromaticity coordinates (0.38, 0.29) when excited at 340 nm.

Halogen substituents on cyanoformamidine ligands and oxyanions affect the structures of complexes due to differences in their electronegativity and volume.
