Abstract: In this study, aromaticity of a 14-membered metal–ligand ring present in a two-dimensional coordination polymer (2D CP), [Zn2(fum)2(4-phpy)4(H2O)2] (1) (H2fum = fumaric acid and 4-phpy = 4-phenyl pyridine), was theoretically investigated by calculating the nucleus-independent chemical shifts (NICS). Furthermore, the calculation was supported by free of in-plane component NICS (FiPC-NICS) used specifically for inorganic heterocycle and electron localization function (ELF) analysis. The calculations reveal that the metal–ligand ring has an aromatic character and a moderate C–Hp interaction energy (8.56 kcal mol1 at the HF/6-311++G(d,p) level of theory) of 4-phpy with the 14-membered ring, which plays an active role in the molecular self-assembly for crystal packing. Furthermore, the compound 1 has a substantive photosensitivity with an appreciable on–off ratio; therefore, this material can be used as a photosensitive electronic device.
