Abstract:A new tetranuclear Co(II) cubane cluster 1, [Co4(L1)4(L2)4]·4CH3CH2OH (HL1 = 2-Methylquinolin-8-ol, HL2 = t-Bu-COOH), has been synthesized and characterized by X-ray single crystal diffraction, FT-IR, TG/DSC, and elementary analysis. The data reveals that it has a very interesting structural motif consisting of a [Co4O4] core in the form of a cube with the Co and O occupying opposite corners. In the crystal structure of complex 1, the molecules are linked by intramolecular C−H···O hydrogen bonding interactions… Show more
