摘要
The reaction of cadmium amalgam with excess of 3,6-di-tert-butyl-o-quinone (3,6-Q) in THF afforded the new bis-o-semiquinonato cadmium(II) complex coordinated with one molecule of neutral o-quinone (3,6-SQ)(2)Cd(3,6-Q) (1) acting as a starting reagent to other bis-o-semiquinonato cadmium(II) complex with N-heterocyclic carbene (NHC)-(3,6-SQ)(2)Cd{C[N(Ar)(CH)](2)} (Ar = 2,6-dimethylphenyl) (2). Both complexes possess a singlet ground state with thermally accessible triplet state (the singlet-triplet gap is 8 cm(-1) for 1 and 132 cm(-1) for 2) as confirmed by magnetic data. The antiferromagnetic exchange SQ-SQ is observed for both complexes. (C) 2014 Elsevier B.V. All rights reserved.
