2014 Elsevier B.V. All rights reserved. Reactions of Ru2n+ [n = 4 for Ru2(OAc)4 and n = 5 for Ru2(OAc)4Cl] with H2CDC (9H-3,6-carbazoledicarboxylic acid), H2BBDC (5-tert-butyl-1,3-benzenedicarboxylic acid) and H2BDC (1,3-benzenedicarboxylic acid) were conducted in inert atmospheres under solvothermal conditions in a sealed tube. Two octahedral cages, [Ru2(CDC)2Cl]6, 1 and [Ru2(CDC)2]6, 2 were obtained when starting from Ru2n+ with CDC, and two cuboctahedral cages, [Ru2(BBDC)2Cl]12, 3 and [Ru2(BDC)2]12, 4 were yielded when starting from Ru2n+ with BDC based linkers. Structures of these MOPs were characterized by single crystal X-ray analyses. The resulted MOPs have shown redox activity and magnetic properties similar to their parent metal complexes.
