The syntheses of the complexes [RuII(terpy)(BIQN)Cl]ClO4(1) and [RuII(terpy)(BIQN)(OH2)](ClO4)2(2) are described. The structure of 1 has been established by X-ray crystallography. The dihedral angle between the two isoquinoline rings is 37.4°. In aqueous solution, [RuII(terpy)(BIQN)(OH2)](ClO4)2shows two reversible/quasi-reversible oxidation couples assigned to the oxidation of ruthenium(II) to ruthenium(III) and ruthenium(III) to ruthenium(IV). [RuII(terpy)(BIQN)(OH2)](ClO4)2is an active catalyst for the oxidation of alkenes by PhIO.
