Abstract
The crystal structure of [{NiL(HL)}2][PF6]2·0.5MeCN·0.5Et2O [HL = 6-(2-hydroxyphenyl)-2,2′-bipyridine] shows that the near-octahedral NiL2 units, with cis-N4O2 geometries, are associated into dimers via strong hydrogen bonding between the phenolate oxygen atoms of two NiL(HL) units; the proximity of the monomer units in the dimer results in an inter-ligand stacking interaction between parallel aromatic rings.Keywords
