Synthesis and Crystal Structures of the Reaction Products of the Magnesium Acenaphthenediimine Complex with Tosyl Azide

Abstract

The reaction of [(Dpp-Bian)Mg(THF)₃] (I) (Dpp-Bian is 1,2-bis[(2,6-diisopropylphenyl)imino]acenaphthene) with tosyl azide (TosN₃) affords the binuclear amide complex [(Dpp-Bian)Mg(THF)(NTos)(THF)Mg(Dpp-Bian)] (II) in which the magnesium atoms are linked with the nitrogen atom by the bridging p-tolylsulfamide group. In the presence of pyridine, the reaction leads to the compound [(Dpp-Bian)Mg(Py)(NTos)(Py)Mg(Dpp-Bian)] (III) in which NTos has different coordination modes with the metal atoms. The diimine ligand is in the radical anion state in both compounds. New paramagnetic compounds II and III are characterized by IR spectroscopy, EPR spectroscopy, elemental analysis, and X-ray diffraction analysis (СFА files CCDC no. 1878433 (II · 1.5C₅H₁₂) and 1878432 (III · 2C₇H₈ · 0.5OC₄H₈)).
