摘要：

The reaction of meso-tetraphenylporphyrina: tomanganese(II) (MnTPP) and. N,7,7-tricyanoquinomethanimine (TCQMI) forms {[(MnTPP)-T-III](+)}(2)[TCQMI](2)(2-), which possesses a one-dimensional chain with mu(1,3)-NCN linkages. The reduced [TCQMI](center dot-) dimerizes as [TCQMI](2)(2-) with a long, central 1.611(8) angstrom C-C bond and leads to a honeycomb, two-dimensionally layered structure with 24-membered rings. The mu(1,3)-NCN linkage stabilizes a canted antiferromagnetic (weak ferromagnetic) behavior with T-c of 3.7 K.
