摘要

Diastereopure (1R,2R)-N,N'-bis(acetylacetone)cyclohexanedi-imine L-1 and its corresponding (1R,2R)L-1/(1S,2S)L-2 enantiomeric mixture react with AgNO3 to yield the unusual coordination polymer [Ag-2(L-1)(L-2)(NO3)(2)](n) (1) and the unique trimetallic discrete species {[Ag-3(L-1)(3)(mu(3)-O,O,O-NO3)(H2O)(3)](2)(NO3)}(NO3)(3)center dot 8.5H(2)O (2) which incorporates a symmetrical mu(3)-bridging nitrato group that gives rise to a C-3-symmetric triskelion motif; both species also feature gamma-carbon eta(1) aryl-like coordination of neutral bridging acetylacetone-imine units to the respective Ag(I) centres.
