The compound [Cu5(μ3-OH)2(H2bpmp)2(μ1,1-OAc)2(μ1,1,3-OAc)2(OAc)2]*2H2O (1*2H2O) (H3bpmp = 2,6-bis-[(3-hydroxy-propylimino)-methyl]-4-methyl-phenol), featuring two fused defective cubanes at a Cu2+ vertex, has been obtained via μ3-OH-bridge-driven self-assembly of two dinuclear Cu(II) phenoxido-bridged {Cu2(H2bpmp)} fragments. Antiferromagnetic interactions within the complex lead to an ST = ½ ground state for the pentanuclear arrangement.
