Abstract
- International audience; An unprecedented two-dimensional honeycomb network based on fused triacontanuclear heterometallic wheels of 3.4 nm, {[Co2(Mn3O (N3)2(pic)6(NO3)]-}6 (Hpic = picolinic acid), has been assembled. The hexagonal {Co12Mn18} wheel motif is composed of six oxo-centered {Mn3} trinuclear and six {Co2} dinuclear moieties acting as nodes and linkers, respectively. The paramagnetic properties of this compound observed down to 1.8 K result from the competition of Mn...Mn, Mn...Co and Co...Co interactions in combination with spin–orbit coupling and single-ion behavior of the Co(II) centers.
