A new (63)•(69.81) non-interpenetrated paramagnetic network with helical nanochannels based on a tricarboxylic perchlorotriphenylmethyl radical

The reaction of a 3-connecting PTMTC radical and a 2-connecting 4,4'-bipyridine ligands with Co(MeCOO)(2).4H(2)O forms a paramagnetic non-interpenetrated supramolecular network, Co(PTMTC)(4,4'-bpy)(H2O)(3).6EtOH.2H(2)O (MOROF-2), with an unprecedented (6(3)).(6(9).8(1)) topology exhibiting helical nanochannels.
