Synthesis, structure and magnetic properties of copper(II) complexes of 2-amino-5-trifluoromethylpyridine (5-TFMAP): (5-TFMAP)2CuX2 (XÂ =Â Cl or Br), (5-TFMAP)3CuBr2 and [(5-TFMAP)2CuBr2](5-TFMAPH)Br

Copper(II) chloride and bromide complexes of 2-amino-5-trifluoromethylpyridine (5-TFMAP) have been prepared and characterized structurally and magnetically [(5-TFMAP)2CuX2, X = Cl, Br; (5-TFMAP)3CuBr2]. The chloride complex is well modeled as an alternating antiferromagnetic chain while the tris-complex is well described as a uniform antiferromagnetic chain with moderate interactions (J = −31 K) via the two-halide pathway.
