Novel di- and trinuclear Rh complexes, [Rh2(PPh3)4(H)4(Me2CO)2(µ-pyz)](ClO4)2·EtOH and [Rh3(PPh3)6(µ-pyz)3](ClO4)3·EtOH were selectively isolated from the reaction of [Rh(PPh3)2(H)2(Me2CO)(EtOH)]ClO4 with pyrazine (pyz) in Me2CO and THF, respectively. Their structures were crystallographically characterized.
