Syntheses, crystal structures and quantum chemistry of two Th(IV) complexes based on the diacylhydrazone ligand

Two Th (IV) complexes {[4-NO2-C6H4(O)C= N-N = C(R)-(R)C= N-N = C(O)-(4-NO2-C6H4)](2)Th(CH3OH)(2)} ( R = Ph ( I ); CH3 (II))were synthesized and characterized by IR, elemental analysis and thermal stability analysis, and the crystal structures were determined by X-ray diffraction. The Th in the complexes I and II adopt ten coordination configuration. Complex I and II also forms a two-dimensional network structure through the abundant hydrogen bond interaction of C -H on the benzene ring with O atom on NO2- groups. The UV-vis and quantum chemical calculations of I and II have been investigated. (c) 2021 Elsevier B.V. All rights reserved.
