Abstract

The reaction of (dpp-BIAN)Mg(THF)3 (1) with anhydrous CrCl3 in THF at 80 °C affords the mixed chromium–magnesium complex (dpp-BIAN)Cr(μ-Cl)3Mg(THF)3 (2). The treatment of 2 with 1,4-dioxane causes the elimination of MgCl2 and the formation of dimeric [(dpp-BIAN)Cr(μ-Cl)(THF)]2 (3). The reaction of (dpp-BIAN)Na2 with CrCl3 gives the chlorine-free compound [Na(THF)6][(dpp-BIAN)2Cr] (4). Paramagnetic complexes 2, 3 and 4 have been characterized by IR and electronic absorption spectroscopy. The magnetic susceptibilities of 2 and 4 have been determined in solution using Evans’ method. The molecular structures of 2–4 have been established by single crystal X-ray analysis.
