 Phenazine and magnesium in tetrahydrofuran (thf) at ca. 20°C afforded a paramagnetic complex, [Mg(C12H8N2) 2(thf)3] (1), and in the presence of magnesium bromide diamagnetic [Mg(C12H8N2)(thf)2] (2), then [Mg2Br2(C12H8N 2)(thf)6] co-crystallized with [MgBr2(thf) 4] (1: 1) (3); single crystal X-ray data revealed the phenazine-containing complex (3) to be monomeric, with two five-co-ordinate magnesium centres each bound to an N-centre 0.48 Å out of the 'phenazine' plane [Mg-N 2.052(7), Mg-Br 2.513(3), and Mg-O 2.066(5)-2.166(5) Å].
