Abstrakt: Controllable synthesis of sophisticated aggregations has attracted wide attention from scientists. In this work, homo- and heterometallic {CoIIICoII12MII6} (M= CoII/CdII) aggregates with similar skeletons, composed of two [Co3M3(dpbt)3] peripheries and a central [Co7(OH)8] vertex-fused double-cubane, were constructed from prefabricated {Co14} clusters and characterized by single-crystal X-ray diffraction and XPS, ICP-MS, SEM (EDX), and so on. And then, the structure and magnetic differences of them had been further analyzed under dotted with paramagnetic CoIIions and/or diamagnetic CdIIions. Interestingly, the spin canting behavior in {CoIIICoII18}was suppressed in {CoIIICoII12CdII6}, upon the introducing of CdIIions.
