mer and fac isomerism in tris chelate diimine metal complexes.
Dabb SL, Fletcher NC. Dabb SL, et al. Dalton Trans. 2015 Mar 14;44(10):4406-22. doi: 10.1039/c4dt03535f. Dalton Trans. 2015. PMID: 25600485 Review.
Diimine ligands have long been the workhorse of coordination chemistry, and whilst there are now good strategies to isolate materials where the inherent metal centered chirality is under almost complete control, and systematic methodologies to isolate heteroleptic complexes, the …
