Abstract
The reaction of NEt(4)[Ir-4(CO)(11)X] (X = Br, I) with aromatic diamines, N-N, in the presence of Ag+ salts affords the first examples of diamino-carbonyl complexes Ir-4(CO)(10)(N-N), (N-N)= 1,10-phenanthroline (1), 4,7-dimethylphenanthroline (2), 5,6-dimethylphenanthroline (3), 3,4,7,8-tetramethylphenanthroline (4), 2,2'-bipyridine (5), 4,4'-dimethyl-2,2'-bipyridine (6). The crystal and molecular structures of 1 and 6 show that the diamine ligands chelate a basal iridium atom in the cluster.File in questo prodotto:
