A new inorganic-organic hybrid based on γ-[Mo8O26]4–, [Zn(H2O)2(H2PIDC)2][(Mo8O26)(HPIM)2]·8H2O (1), (H2PIDC = 2-(pyridine-3-yl)-1H-imidazole-4,5-dicarboxylic acid; PIM = 2-(pyridine-3-yl)-imidazole), has been synthesized and structurally characterized by X-ray single-crystal diffraction. PIM was synthesized through in situ decarboxylation reaction from H2PIDC. The two five-coordinated Mo atoms of γ-[Mo8O26]4– are coordinated with two HPIM+ forming a [(Mo8O26)(HPIM)2]2− unit. [Zn(H2O)2(H2PIDC)2]2+ units and [(Mo8O26)(HPIM)2]2− units are linked into a 3D supramolecular structure by noncovalent interactions. The Hirshfeld surface analyses indicates that hydrogen bonding interactions are the dominant interactions in 1. The solid-state luminescence spectrum of compound 1 at room temperature was investigated (λem = 395 nm). We have also studied the cyclic voltammograms and the electrocatalytic reduction of KNO2 of 1-CPE. [Display omitted]
