Abstract

The reaction of Ni(NO₃)₂·6H₂O with Na₂SeO₃ in the presence of tetramethylethylenediamine (TMEDA) in a water/ethanol mixture yielded the heteroleptic complex [{Ni(TMEDA)SeO₃}₂] (1). Single-crystal X-ray diffraction analysis showed that complex 1 consists of a dinuclear species in which the two nickel atoms are held together by two bridging selenito anions. The crystal packing of 1 is determined by networks of hydrogen bonds, involving cocrystalized water molecules and the oxygen atoms of the bridging SeO ₃^2- groups. The two nickel ions in 1 exhibit antiferromagnetic coupling with J = -25.7 ± 0.1 cm^-1, in good agreement with DFT calculations. In addition, when a less sterically hindered ancillary ligand, such as ethylenediamine (en), was used, the homoleptic complex [Ni(en)₃](SeO₃) (2) was obtained. The reaction of Ni(NO₃)₂·6H₂O with Na ₂SeO₃ in the presence of tetramethylethylenediamine (TMEDA) yielded the heteroleptic complex [{Ni(TMEDA)SeO₃} ₂]. The two nickel ions exhibit antiferromagnetic coupling with J = -25.7 ± 0.1 cm^-1, in good agreement with DFT calculations.
