Quantum-Chemical Simulation of the Structure of Charge-Transfer Complexes of 9,10-Phenanthrenequinone Nitro-Derivatives with Phenanthrene. Crystal and Molecular Structure of 1 : 1 Complex of 2,4,7-Trinitro-9,10-phenanthrenequinone with Phenanthrene

Abstract: Data on the structure and properties of charge transfer complexes of nitro derivatives of 9,10-phenanthrenequinone (acceptor) with phenanthrene (donor) were obtained by quantum chemical calculations. The energies of complex formation, the average distances between donor and acceptor planes, and the total charge transfer amounts were calculated. 1,3,6-Trinitro-9,10-phenanthrenequinone was shown to be the strongest acceptor in the studied series. The crystal and molecular structure of the 1 : 1 complex of 2,4,7-trinitro-9,10-phenanthrenequinone with phenanthrene [C14H5N3O8·C14H10] was determined by X-ray structural analysis. © 2020, Pleiades Publishing, Ltd.
