Synthesis and Gas Occlusion of New Micropore Substance Rhodium(II) Carboxylates Bridged by Pyrazine

Novel donor/acceptor-type tetrathiafulvalenes, tetrathiafulvaleno-quinonemethide and -thioquinonemethide were synthesized, which are expected as new (pi) donor molecules bearing d local spin, because they can capture several magnetic metal ions through binding with the carbonyl oxygen or thiocarbonyl sulfur atom.
