Hydrothermal Synthesis and Structure of a Three-Dimensional Cobalt(II) Triazolate Magnet Academic Article uri icon

abstract

  • 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.
