| - For the first time, paddlewheel complexes with Ir25+ cores and having an unpaired electron have been made in relatively good yield.
- Paddlewheel complexes with Ir25+ cores and having an unpaired electron have been made for the first time.These have been prepared by reacting (COD)IrI(DArF)2IrIII(CF3CO2)2(H2O) with two molar equivalents of HDArF(DArF = N,N‘-diarylformamidinate, Ar = p-anisyl and p-chlorophenyl, and COD = 1,5-cyclooctadiene). In thepresence of CH2Cl2, the corresponding Ir2(μ-DArF)4(η1-O2CCF3)·2CH2Cl2 compounds are isolated in ca. 50%yield. The metal−metal distances are 2.5073(9) and 2.513(1) Å for the p-anisyl and p-chlorophenyl derivatives,respectively. We also report the structure of the dinuclear compound [Ir2(cis-μ-DAniF)2(MeCN)6](BF4)2·2CH3CN, which has an IrIr bond distance of 2.6019(4) Å, and that of a starting material, [Ir(DAniF)(COD)]2·toluene.
