Synthesis, Characterization and Anticancer Activity of Porphyrin-Containing Organometallic Cubes

Self-assembly of 5,10,15,20-tetra(4-pyridyl)porphyrin (tpp-H2) and 5,10,15,20-tetra(4-pyridyl)porphyrin-M(II) (MNi (tpp-Ni); Zn (tpp-Zn)) tetradentate panels with the dinuclear p-cymene ruthenium clips [Ru2(p-cymene)2(C2O4)Cl2] and [Ru2(p-cymene)2(C6H2O4)Cl2] (C2O4 oxalato; C6H2O4 2,5-dioxydo-1,4-benzoquinonato) affords the cationic organometallic cubes: [Ru8(p-cymene)8(tpp-H2)2(C2O4)4
