To investigate the influence of a secondary spacer on the resulting structures of POMOFs containing pytz, five new compounds with different dimensionalities, [Cu5(2-pytz)6(H2O) 4][SiMo12O40]·3H2O (1), [Cu3(2-pytz)4bipy][H2SiMo12O 40]·bipy (2), [Cu3(2-pytz)2(bipy) 4(H2O)6][H4SiW12O 40]2·6H2O (3), [Cu2(2-pytz) (phen)(OH)]2[SiW12O40]·H2O (4), [Cu3(4-pytz)4(H2O)4][H 2SiW12O40]·2H2O (5), were synthesized. When only 2-pytz was employed, compound 1 with a 3D framework was obtained, whereas when the secondary spacers (4,4′-bipy, phen and 4-pytz) were introduced into the reaction system of 1, compounds 2-5 were obtained and exhibit a broad range of structures, including 0D, 1D, 2D and 3D frameworks. It can be observed from the architectures of compounds 1-5 that the secondary spacers have a great effect on the structures of the MOFs, which results in the formation of various dimensional POMOF compounds. Additionally, photocatalytic experiments of 1-5 for the photocatalytic degradation of RhB under UV irradiation were also investigated. © The Royal Society of Chemistry 2013.
