Discrete and encapsulated molecular grids: Homometallic Mn15 and heterometallic Mn24Ni2 aggregates
(2014)Two molecular grid-like clusters are reported, one is a discrete [3 × 5] grid and the other a [3 × 4] grid within a Mn12Ni 2 loop. Both Mn24Ni2 and Mn15 aggregates display novel and aesthetically pleasing structures with ...

A [Mn32] double-decker wheel
(2011)Inventing the double wheel: A mixed-valent [Mn32] cluster with a very rare "double-decker" wheel topology (see its metal-oxygen core: MnIII blue, MnII pink, O red) is reported. It is by far the highest-nuclearity example ...
