The title compound, $[Er(C_5H_7O_2)_3(C_{12}H_8N_2)]$, is a mixedligand 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 $C-H^{...}\pi$ 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.
