A three-dimensional Co(II) metal–organic framework {[Co5(btec)2(btx)(μ3-OH)2(H2O)2]·2H2O}n (1) (H4btec=1,2,4,5-benzenetetracarboxylic acid, btx=1,4-bis(1,2,4-triazol-1-ylmethyl)benzene) containing rare pentanuclear Co(II)-clusters has been hydrothermally synthesized and structurally characterized, and shows an unusual binodal (4,10)-connected topology. The fluorescence properties and catalytic activity of the complex for degradation of methyl orange in the Fenton-like process were investigated.
