摘要
A series of chain complexes of rhodium(II) trifluoroacetate, [Rh-2(O2CCF3)(4)(P-Q)](n) (P-Q=1,4-benzoquinone (1,4-bq), 1,4-naphthoquinone (1,4-nq), and 2,3-dimethyl-1,4-benzoquinone (2,3-dmbq)) have been prepared. The chain structures were confirmed by the X-ray structure analyses. The carbonyl oxygens of the p-quinones are coordinated to the Rh-2 centers with the distances of 2.248(5) (for p-Q=1,4-bq), 2.248(3) (for p-Q=1,4-nq), and 2.247(9) Angstrom (for p-Q=2,3-dmbq), respectively. The bridging mode of the p-quinone was discussed in relation to the substituent effect of CS group on the carboxylate.
