Abstract
Two 3D coordination polymers, [Co<sub>24</sub>(OH)<sub>12</sub>(SO<sub>4</sub>)<sub>12</sub>(ip)<sub>6</sub>(DMSO)<sub>18</sub>(H<sub>2</sub>O)<sub>6</sub>]·(DMSO)<sub>6</sub>(EtOH)<sub>6</sub>(H<sub>2</sub>O)<sub>36</sub> (<b>1</b>·guests,
ip = isophthalate) and [Ni<sub>24</sub>(OH)<sub>12</sub>(SO<sub>4</sub>)<sub>12</sub>(ip)<sub>6</sub>(DMSO)<sub>12</sub>(H<sub>2</sub>O)<sub>12</sub>]·(DMSO)<sub>6</sub>(EtOH)<sub>6</sub>(H<sub>2</sub>O)<sub>20</sub> (<b>2</b>·guests), constructed
with nanosized tetraicosanuclear Co<sup>II</sup> and Ni<sup>II</sup> wheels are solvothermally synthesized. Both complexes show intra-
and interwheel dominant antiferromagnetic interactions
