Abstract
Reaction of tetrakis(pivalato)diruthenium(II,III) cation dimer and 9,10-anthraquinone (aq) gave two kinds of adducts, [{Ru2(piv)4(H2O)}2(aq)]-(BF4)2 (1) (pivH = pivalic acid) and [Ru2(piv)4(aq)] n (2), depending on the condition. Very weak antiferromagnetic interaction was observed for 1. The X-ray crystal structure of 2 shows an one-dimensional chain structure.
