چکیده

The reaction of CoCl2.6H2O, 1,2,4-triazole, and H(2)O at 200 degrees C for 96 h yields purple rods of [Co2(trz)3Cl] (1; trz = 1,2,4-triazolate) in 90% yield. The structure of 1 consists of {Co(trz)3}n(n-) chains of Co(II) sites linked through tetrahedral sites of {CoN(3)Cl} geometry into a three-dimensional framework. The competing antiferromagnetic interactions of the octahedral and tetrahedral Co(II) centers result in weak ferromagnetic behavior below Tc = 9 K.

Poly[(3-nitro­benzoato)(μ3-1,2,4-triazolato)cobalt(II)]

In the title compound, [Co(C(2)H(2)N(3))(C(7)H(4)NO(4))](n), the Co(II) atom is five-coordinated by three triazolate ligands and one bidentate 3-nitro-benzoate anion in a distorted trigonal-bipyramidal geometry. The triazolate ligand bridges the Co(II) atoms, generating a two-dimensional net parallel to the ab plane, in which both the Co(II) atom and the triazolate ligand act as three-connected...
