Four novel 2D complexes M2(Hptim)2(HBTC)2 [M = Co (1), Cd (2), Zn (3), Mn (4); Hptim = 2,4,5-tri(4-pyridyl)-imidazole; HBTC2– = Benzene-1,3,5-tricarboxylic acid] were synthesized under solvothermal conditions. The four complexes are isomorphous and present a unique structure with a 1D ladder of [Co2(HBTC)2]n. The 2D network structure of 1 is achieved through bridging Hptim groups, which coordinate to the metal atoms of two adjacent 1D [Co2(HBTC)2]n ladders. Magnetic measurements reveal that dominant antiferromagnetic coupling was observed in compounds 1 and 4. Compounds 2 and 3 both exhibit strong fluorescent emissions in the solid state and may be suitable candidates for fluorescent materials.
