| Abstract: | The reactions of monomeric complexes (dpp-bian)M(THF)n](M = Mg, n = 3; M = Ba, n = 5; dpp-bian = 1,2-bis(2,6-di-isopropylphenyl)imino]acenaphthene) with 4,4'-bipyridine (4,4'-bipy) in THF proceed with electron transfer from dpp- bian2– to 4,4'-bipy0 to afford 1D coordination polymers (dpp-bian)M(4,4'-bipy)(THF)n]m (M = Mg, n = 1; M = Ba, n = 2) that contain simultaneously radical anion ligands dpp-bian– and 4,4'-bipy . Addition of DME to coordination polymer (dpp-bian)Mg(4,4'-bipy)(THF)n]m results in fragmentation of polymeric chains to give dinuclear magnesium species {(dpp-bian)Mg(DME)}2(4,4'-bipy)]. Barium analogue {(dpp-bian)Ba(DME)2}2(4,4'-bipy)] has been prepared by reacting of complex (dpp-bian)Ba(DME)2.5] with 4,4'-bipy in DME. |
