Abstract

The new phenol–imidazole pro-ligands RLH react with Co (BF4) 2· 6H2O in the presence of Et3N to form the corresponding [CoII (RL) 2] compound (R= Ph (1), PhOMe (2), or Bz (3)). Also, BzLH, reacts with Co (II) in the presence of Et3N and H2O2 to form [CoIII (BzL) 3](4). The structures of 1· 2.5 MeCN, 2· 2DMF, 3· 4MeOH, and 4· 4DMF have been determined by X-ray crystallography. 1, 2, and 3 each involve Co (II) bound to two N, O-bidentate ligands ...
