Graf, Marion; Siegmund, Daniel; Metzler‐Nolte, Nils and Sünkel, Karlheinz (2019): Bis‐cyclometalated Rhodium and Iridium Chloride Complexes Yield Different Products Upon Reaction With 9,10‐Diaminophenanthrene. In: Zeitschrift für Anorganische und Allgemeine Chemie, Vol. 645, No. 17: pp. 1068-1071 [PDF, 451kB]


The reaction of 9.10‐diaminophenanthrene with [{Rh(μ‐Cl)(ptpy)2}2] yields – quite unexpected – the new cyclometalated complex salts [Rh(ptpy)2(9,10‐diiminophenanthrene)]PF6 (1), whereas with the corresponding dinuclear iridium compound the “usual” [Ir(ptpy)2(9,10‐diaminophenanthrene)]PF6 (2) is obtained. The molecular structure of compound 1 was confirmed by single‐crystal X‐ray diffraction. 1 crystallized in the monoclinic space group P21/n as a dichloromethane solvate. Both compounds display significant cytotoxicity against human cancer cell lines with the IC50 values in the low micromolar range.
