Abstract

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