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 [Ag2(L 1)(L 2)(NO3)2]n (1) and the unique trimetallic discrete species ([Ag3(L 1)3(μ3-O,O,O-NO3)(H2O)3]2(NO3))(NO3)3·8.5H2O (2) which incorporates a symmetrical μ3-bridging nitrato group that gives rise to a C3-symmetric triskelion motif; both species also feature γ-carbon η1 aryl-like coordination of neutral bridging acetylacetone-imine units to the respective Ag(I) centres. © 2009 The Royal Society of Chemistry.
