title: A magnetically highly frustrated Cu(II)27 coordination cluster containing a Cu18 folded-sheet motif.
abstract: [Cu(II)27(μ4-O)2(OH)13(OMe)7(vanox)10(NO3)8(OH2)2(MeOH)7](NO3)2·2H2O·11MeOH (1) was synthesised from Cu(NO3)2·3H2O and o-vanillin-oxime. Structural analysis shows a molecule composed of a Cu18 "folded-sheet" motif linked to a Cu9 bridging unit. The cluster is highly frustrated and has an S = 1/2 spin ground state.
