Synthesis and X-ray crystal structures of [pyH][Fe(pic)2Cl2] and [Fe2(μ2-OMe)2(pic)4] (Hpic=2-picolinic acid)

The passage of dichlorine gas through a dichloromethane solution of [Fe(pic)2(py)2] gives [pyH][Fe(pic)2Cl2] (1) whilst the methoxy bridged diiron(III) complex 2 was prepared and crystallised directly from the reaction of [Fe(pic)2(py)2] with methanol in air. The X-ray structures of 1 and 2 are reported.
