A series of chain complexes of molybdenum(II) trifluoroacetate linked by <i>p</i>-quinones, [Mo<sub>2</sub>(O<sub>2</sub>CCF<sub>3</sub>)<sub>4</sub>(<i>p</i>-quin)]<sub><i>n</i></sub>, <i>p</i>-quin = 9,10-anthraquinone (9,10-aq), 2,6-dimethyl-1,4-benzoquinone (2,6-dmbq), and 1,4-naphthoquinone (1,4-nq) have been prepared. The X-ray structure analyses showed that the carbonyl oxygens of the <i>p</i>-quinones are coordinated to the Mo<sub>2</sub> dimers with distances of 2.478(6) and 2.532(5) &Aring; (for 9,10-aq), 2.619(9) and 2.596(10) &Aring; (for 2,6-dmbq), and 2.522(8) &Aring; (for 1,4-nq), respectively. The Mo&ndash;Mo bond distances are 2.107(1)&mdash;2.117(1) &Aring;, which are slightly longer than that of Mo<sub>2</sub>(O<sub>2</sub>CCF<sub>3</sub>)<sub>4</sub> (2.090(4) &Aring;). Elongation of the C=O and C=C bonds of the 9,10-aq and 2,6-dmbq molecules on the coordination has been observed, but the bond distances of the coordinated and uncoordinated 1,4-nq molecules are similar to each other. The difference is discussed in terms of the oxidizing abilities and the symmetries of the <i>p</i>-quinones.
