Three 1D copper(I/II) complexes of 4,6-dipyridyl-2-aminopyrimidine: Effect of the ligand isomerism on the structural motif

By using three ligand isomers H2L1, H2L2, and H2L3 [H2L1 = 4,6-bis(2-pyridyl)-2-aminopyrimidine, H2L2 = 4-(2-pyridyl)-6-(3-pyridyl)-2-aminopyrimidine, H2L3 = 4-(2-pyridyl)-6-(4-pyridyl)-2-aminopyrimidine], three copper (I/II) complexes with different structural motifs were synthesized and characterized by single-crystal X-ray diffraction.
