Abstract: | The title compound, Er(C5H7O2)3(C12H8N2)], is a mixed‐ligand metal–organic precursor for chemical vapour deposition, with the Er atom being eight‐coordinate. The coordination polyhedron, described as a distorted square antiprism, is formed by three bidentate (chelating) acetylacetonate residues and a phenanthroline ligand in the apical positions. Molecular assembly via C—H?O hydrogen bonds generates a sheet structure in the ac plane. Weak co‐operative C—H?π interactions form molecular dimers and contribute to the stability of the intersheet packing. The supramolecular assembly contains voids which form hydrophobic porous channels, surrounded by a cluster of dimers. |
