摘要：
The cobalt(II) chloro complex with 1-allyhetrazole (Alltz) Co(Alltz)(2)Cl-2 was studied by the magnetic susceptibility measurements and X-ray diffraction analysis. The coordination polyhedron of the complex is a distorted octahedron formed by the N(4) atoms of two Alltz cycles and four bridging Cl atoms (coordination unit CoN2Cl4). Each chlorine atom is bound with two cobalt atoms giving rise to a crimped polymeric network. The Co(Alltz)(2)Cl-2 complex is a weak ferromagnetic with T-N = 102 +/- 1 K and spontaneous magnetization sigma(S)(5 K) = 710 +/- 5 G cm(3) mol(-1). Hysteresis effects, depending on the intensity of the magnetic field in which the sample was cooled, were detected.
