  Ligand substitution in hexahalorhenate(IV) complexes: Synthesis, crystal structures and magnetic properties of NBu4[ReX5(DMF)] (X=Cl and Br)

  摘要：

  The preparation, crystal structures, and magnetic properties of two rhenium(IV) mononuclear compounds of formula NBu4[ReX5(DMF)](NBu4+ = tetrabutylammonium cation and DMF = N, N-dimethylformamide) with X = Cl (1) and Br (2) are reported. 1 and 2 are isostructural complexes which crystallize in the monoclinic system with the space group P2(1)/n. The rhenium atom is six-coordinated with five X atoms and a DMF molecule forming a somewhat distorted octahedral surrounding [values of Re X varying in the ranges 2.317(1)-2.358(1) (1) and 2.495(1)-2.518(1) angstrom (2)]. Magnetic susceptibility measurements on samples of 1 and 2 in the temperature range 1.9-300 K are interpreted in terms of magnetically isolated spin quartets with large values of the zero-field-splitting (vertical bar 2D vertical bar is ca. 20.2 and 39.2 cm(-1) for 1 and 2, respectively).
