The first metal complexes of 4,4'-biimidazole and 4,4'-biimidazolate with hydrogen-bonding networks on the Cu(II) complexes: 1-D structures by N-H center dot center dot center dot X center dot center dot center dot H-N hydrogen-bonding
The Cu(II) complexes based on 4,4'-biimidazole and its deprotonated mono-anionic ligands were synthesized as the first metal complexes, which exhibit hydrogen-bonding networks. X-ray crystal structure analyses reveal the pi-stacking structure of each complex and N-H...X or N...H-X type hydrogen-bondings.
