The reaction of 2,3-di(2-pyridyl)-5,6-diphenylpyrazine
(dpdpz)
with Re(CO)5Cl in acetonitrile or toluene afforded mono-Re
and bis-Re complexes [Re(CO)3Cl-dpdpz] and [Re(CO)3Cl-dpdpz-Re(CO)3Cl], respectively. A heterodinuclear
complex [Ru(bpy)2-dpdpz-Re(CO)3Cl](PF6)2 could be prepared by the reaction of [Re(CO)3Cl-dpdpz] with Ru(bpy)2Cl2 or the reaction
of Re(CO)5Cl with a previously reported mono-Ru complex
[Ru(bpy)2-dpdpz](PF6)2 in moderate
yields. Surprisingly, the reaction of [Re(CO)3Cl-dpdpz]
or [Re(CO)3Cl-dpdpz-Re(CO)3Cl] with Ru(tpy)Cl3 in the presence of AgOTf both afforded an asymmetric bis-Ru
complex [Ru(tpy)-dpdpz-RuCl(tpy)](PF6)2. The
solid-state structures of [Re(CO)3Cl-dpdpz-Re(CO)3Cl] and [Ru(tpy)-dpdpz-RuCl(tpy)](PF6)2 were
determined by single-crystal X-ray analysis. The electrochemical,
absorption, and emission properties of these compounds were studied
by cyclic voltammetric and spectroscopic analyses. In addition, DFT
calculations were carried out to aid in the interpretation of these
experimental findings.
