Abstract

A novel decanuclear Co(ii) cluster, [Co ₁₀(Q) ₁₂(μ ₆-CO ₃) ₄]·2.5DMF (1) (Q = 8-hydroxyquinoline), has been synthesized under solvothermal conditions and characterized by powder XRD, TGA and IR spectroscopy. Single-crystal X-ray diffraction analysis shows that 1 represents a new type of decanuclear cobalt cluster with an approximate supertruncated tetrahedral shape coordinated with coexisted Q ligands and in situ formed μ ₆-bridging CO ₃ ^2- anions. Meanwhile, 1 is the largest aggregate in metal-Q coordination chemistry. Another distinguishing feature of 1 is the adamantane-like metallic skeleton with point symbol {6 ³} ₂{6} ₃, which is observed in the polynuclear metal complexes for the first time. Furthermore, it is considered that the in situ formed CO ₃ ^2- anions have a crucial effect on the formation of the resultant unexpected polynuclear structures. The magnetic studies show that antiferromagnetic (AF) interactions exist within 1.
