The reaction of Ru3(CO)12 and 2-phenylpyridine (Hppy) in hot methanol yields the dinuclear ruthenium(II) complex [Ru(OCH3)(ppy)(CO)2]2 (3) in moderate yield. Heating of Ru3(CO)12 and Hppy in a cyclohexane-dimethoxyethane mixture generates the mononuclear complex [Ru-cis- (ppy)2-cis-(CO)2] (2). When 2 is treated with methanol at elevated temperature, only partial conversion into 3 can be achieved. The structures of complexes 2 (two polymorphs) and 3 were established by X-ray diffraction analysis.
