The crystal structures of the title compounds, [Ru-2-(C2H3O2)(2)(C3H4N
2)(2)(CO)(4)], (1), and [Ru-2(C2H3O2)(2)-(C5H8N2)(2)(CO)(4)], (2), hav
e been determined, The octahedral coordination about the Ru-1 ion is s
lightly distorted in (1) and more distorted in (2), with the two O ato
ms and two C atoms in the equatorial positions, and one N atom and ano
ther Ru ion in the axial positions. Compound (2) has mirror symmetry.
