The reaction of [PPN](3)[Re(7)C(CO)(21)] with Hg(2)(NO(3))(2).2H(2)O in dichloromethane formed the complex [PPN](4)[(Re(7)C(CO)(21)Hg)(2)] ([PPN](4)[1]), isolated in 60% yield. Analogous salts of [1](4-) with [PPh(4)](+) and [NEt(4)](+) were also prepared. The crystal structure of [PPN](4)[1] showed that two carbidoheptarhenate cores are linked

Cadmium, mercury and rotenone are environmental pollutants whose neurotoxic mechanisms are not fully understood. We have shown previously that exposure of nerve cells to these agents produces oxidative stress which reversibly blocks growth factor and cytokine-mediated Janus kinase (Jak)/signal transducer
