Construction and Magnetic Difference of {Co^IIICo^II₁₂M^II₆} (M = Co^II/Cd^II) Aggregates with Homo- and Heterometallic Centers Derived from {Co₁₄} Precursors

Controllable synthesis of sophisticated aggregations has attracted wide attention from scientists. In this work, homo- and heterometallic {Co^IIICo^II₁₂M^II₆} (<i>M</i> = Co^II/Cd^II) 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 Co^II ions and/or diamagnetic Cd^II ions. Interestingly, the spin canting behavior in <b>{Co</b>^<b>III</b><b>Co</b>^<b>II</b>_<b>18</b><b>}</b> was suppressed in <b>{Co</b>^<b>III</b><b>Co</b>^<b>II</b>_<b>12</b><b>Cd</b>^<b>II</b>_<b>6</b><b>}</b>, upon the introducing of Cd^II ions.
