Novel stacking in a binuclear iridium carbonyl imidazoledicarboxylate
Abstract
The crystal structure of [Bu4N][lr2(mdcbi)(CO)4]·CH2Cl2(H3mdcbi = 2-methylimidazole-4,5-dicarboxylic acid) shows a new type of stacking in which the two iridium atoms of the binuclear complex are both involved in extended metal–metal chains at nearly identical distances.
