In　this　work,　we　synthesized　two　Cu-based　heterometal-oxo　clusters　1　and　2　based　on　M(III)4O4　(M　=　Fe/In)　cubane　centers　and　obtained　the　corresponding　dimers　3　and　4　by　connecting　Cu　atoms　on　the　cluster　cores　with　the　auxiliary　ligand　4,4′-　bipyridine.　They　were　characterized　by　single-crystal　X-ray　diffraction　(SCXRD),　powder　X-ray　diffraction　(PXRD),　and　other　tests.　We　conducted　magnetic　property　study　on　compounds　1-4.　The　variable-temperature　magnetic　susceptibility　test　shows　that　compounds　1　and　3　exhibit　significant　ferromagnetic　interactions　at　low　temperatures,　while　compounds　2　and　4　exhibit　overall　antiferromagnetic　interactions.　When　the　metal　at　the　cubane　changes　from　magnetic　Fe　to　nonmagnetic　In,　the　magnetic　interactions　in　the　compound　are　weakened　to　a　certain　extent.　Through　dimerization,　the　extreme　values　of　the　variable-temperature　magnetic　susceptibility　appear　(1　to　3)/disappear　(2　to　4)　in　the　low-temperature　section.　We　investigated　the　magnetic　structure　correlation　of　compounds　1-4　through　bond　lengths,　bond　angles,　and　distances　between　magnetic　atoms.　The　results　showed　that　compounds　1-4　exhibited　significant　magnetic　coupling　diversity.　©　2024　American　Chemical　Society.
