Crystal structure and magnetic properties of hexachlororhenates(IV) with aromatic amine cations

Complexes of the form (AH) 2ReCl 6 (A=Py, Qy) are characterized using X-ray studies and magnetic measurements over the 1.72–300 K temperature range. The pyridine and quinoline salts crystallize in the triclinic system and the space group P1̄. All compounds indicating the presence of antiferromagneti...

Description
Summary:Complexes of the form (AH) 2ReCl 6 (A=Py, Qy) are characterized using X-ray studies and magnetic measurements over the 1.72–300 K temperature range. The pyridine and quinoline salts crystallize in the triclinic system and the space group P1̄. All compounds indicating the presence of antiferromagnetic interactions and the magnetic susceptibility curves exhibits the maximum at 4.25 K for (PyH) 2ReCl 6 and at 3.57 K for (QyH) 2ReCl 6·2H 2O. Their octahedral ReCl 6 2− anions are packed with planar amine cations so that the octahedra form alternating layers with the organic moieties, and the usual bond lengths and angles are maintained.
