Chloridobis(1,10-phenanthroline-κ2N,N′)copper(II) tetrakis(nitrato-κ2O,O′)(1,10-phenanthroline-κ2N,N′)terbate(III)

Abstract

The title complex salt, [CuCl(C12H8N2)2][Tb(NO3)4(C12H8N2)], consists of discrete [CuCl(phen))2]+ cations and [Tb(NO3)4(phen)]− anions (phen is 1,10-phenanthroline). The [CuCl(phen))2]+ cation contains a five-coordinate Cu2+ ion, ligated by two bidentate phen ligands and one Cl− ion, exhibiting a distorted CuN4Cl trigonal–bipyramidal geometry. In the [Tb(NO3)4(phen)]− anion, the Tb3+ ion is coordinated by one chelating phen ligand and four chelating nitrates, forming a distorted TbN2O8 bicapped dodecahedral configuration. The anions and cations are assembled into a three-dimensional network by weak C—H...Cl and C—H...O hydrogen bonds. There is also a significant π–π stacking interaction, with a centroid–centroid distance of 3.635 (2) Å.
