In the title compound, [Cu(CHCOO)(CHNO)] , the Cu ion resides on a centre of inversion, displaying a tetra-gonally distorted octa-hedral coordination environment defined by two pairs of N and O atoms of symmetry-related 4-(1-imidazol-1-yl)phenol ligands and the O atoms of two symmetry-related acetate ligands. The bridging mode of the 4-(1-imidazol-1-yl)phenol ligands is associated with a very long Cu⋯O inter-actions involving the phenol O atom of the heterocyclic ligand, which creates chains extending parallel to [100]. In the crystal, the chains are arranged in a distorted hexa-gonal rod packing and are linked C-H⋯O hydrogen bonds and by π-π stacking inter-actions involving centrosymmetrically related pairs of imidazole and phenol rings.

Two-dimensional (2D) materials hold great promise for the next-generation optoelectronics applications, many of which, including solar cell, rely on the efficient dissociation of exciton into free charge carriers. However, photoexcitation in atomically thin 2D semiconductors typically produces exciton with a binding energy of ∼500 meV, an order of magnitude larger than thermal energy at room temperature. This inefficient exciton dissociation can limit the efficiency of photovoltaics.

Distortion results from different Fe-N bond lengths [2.1397 (13)-2.

A new three-dimensional (3D) coordination polymer, namely, poly[diaqua[μ-2,2'-(1,3,5,7-tetraoxo-1,2,3,5,6,7-hexahydropyrrolo[3,4-f]isoindole-2,6-diyl)diacetato]barium(II)], [Ba(CHNO)(HO)], (I), has been synthesized by the microwave-irradiated reaction of Ba(NO) with N,N'-bis(glycinyl)pyromellitic diimide {BGPD, namely, 2,2'-(1,3,5,7-tetraoxo-1,2,3,5,6,7-hexahydropyrrolo[3,4-f]isoindole-2,6-diyl)diacetatic acid, HL}. The title compound was structurally characterized by single-crystal X-ray diffraction analysis and powder X-ray diffraction analysis, as well as IR spectroscopy. In the crystal structure of (I), the Ba ion is nine-coordinated by six carboxylate O atoms from five symmetry-related L dianions and one imide O atom, as well as two water O atoms.
