Abstract

The reaction of CoCl ₂·6H ₂O, 1,2,4-triazole, and H ₂O at 200°C for 96 h yields purple rods of [Co ₂(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 ₃Cl} geometry into a three-dimensional framework. The competing antiferromagnetic interactions of the octahedral and tetrahedral Co ^II centers result in weak ferromagnetic behavior below T _c = 9 K.
