Syntheses, structures and photocatalytic properties of two coordination polymers based on bis(1,2,4-triazol-4-ylmethyl)benzene and multicarboxylates

•Tetranuclear copper(II) cluster [Cu4(μ3-OH)2]•An unusual (3,10)-connected two-dimensional metal–organic framework•An interesting 3D network based on 1D metal–organic nanotube•Good photocatalytic activity for the degradation of methyl blue (MB)•The 1,4-bis(1,2,4-triazol-4-ylmethyl)benzene and multicarboxylate

Two coordination polymers {[Cu4(OH)2(btrb)2(btc)2]·4H2O}n (1) and {[Cd2(btrb)(adc)2(H2O)]·H2O}n (2) were synthesized with hydrothermal method and characterized (btrb = 1,4-bis(1,2,4-triazol-4-ylmethyl)benzene, btc = 1,3,5-benzenetricarboxylate, adc = 1,3-adamantanedicarboxylate). 1 shows an unusual (3,10)-connected two-dimensional metal–organic framework based on the tetranuclear copper(II) cluster [Cu4(μ3-OH)2]. 2 is an interesting three-dimensional network based on the one-dimensional metal–organic nanotube. 1 shows good photocatalytic activity for the degradation of methyl blue (MB). The luminescence of 2 was investigated.
