Reactions of metallic Ba with benzofuranol (dbbfoH) or diethylene glycol give homoleptic and homonuclear complexes Ba(dbbfo)2(dbbfoH)2·3dbbfoH and Ba{O(CH2CH2O)2}{O(CH2CH2OH)2}2 (60−89%). Both compounds and formerly described Ba{O(CH2CH2O)2Me}2 react with Al(CH3)3 to yield trinuclear heterobimetallic low-coordinated barium compounds with structure and geometry depending on the reaction stoichiometry and crystallization procedure.
