(μ-O)(μ-O2CR)2Py4(O2CR)2] (R = C(CH3)3, CH3, Ph, CH2Cl, CCl3, and CF3) were obtained and studied by electronic absorption and IR spectroscopy and FAB mass spectrometry. The carboxylate ions RCO

are symmetrically arranged (trans with respect to the bridging μ-O atom) and coordinated in a monodentate fashion. According to X-ray diffraction data, the
crystals of Ru

(μ-O)(μ-O2CCF3)2Py4(O2CCF3)2] ⋅ (CH3)2CO are monoclinic; the unit cell parameters are a = 11.705(2) Å, b = 16.166(3) Å, c = 20.917(4) Å, β = 103.47(3)°, space group C2/c, Z = 4. The RCO

groups that are trans to the μ-O atom can be easily replaced by pyridine or acetonitrile.
