DFT investigations of AgMC7H10N2 (M = Cl, Br, and I) metal organic molecules: NMR, optoelectronic, and transport properties.

Abstract

The full-potential linearized augmented plane wave (FP-LAPW) method was used for the calculation of the structural, nuclear magnetic resonance (NMR), optoelectronic, and thermoelectric properties of AgMC7H10N2 (M = Cl, Br, and I) compounds. The calculated wide band gap of AgMC7H10N2 (M = Cl, Br, and I) metal organic molecules with the density of states approach were 3.32, 3.29, and 3.10eV, respectively. The NMR parameters are calculated for the Ag, Cl, Br, I, C, N, O, and H elements. It is found that by decreasing bandgap, the isotropic NMR chemical shielding values of Cl, Br, and I elements increase. The strong hybridization of Ag-4d, Cl-3p, Br-4p, and I-5p states are observed at the top of the valence band. The birefringence and anisotropic properties are observed in the optical spectra with high plasmon energies, and the figure of merit, ZT, of 0.98 for AgCl(C7H10N2) compound is found at 300K. Hence, these compounds are attractive flexible metal organic molecules for optoelectronic and transport applications.
