Two open-framework zinc phosphites constructed from different secondary building units

摘要

Presented here are two new zinc phosphites, formulate as Zn-3(dabco)(2)(HPO3)(3) (1, dabco = 1,4-diazabicyclo [2.2.2]octane), and H(2)pmdeta.Zn-3(HPO3)(4) (2, pmdeta = N,N,N',N",N"-pentamethyldiethylenetriamine). Compound 1 has 12-membered-ring (12 MR) channels with a 5-connected bnn topology containing 4 = 1 secondary building units. Compound 2 has multidirectional 10 MR channels with a pcu topology constructed from 6*1 secondary building units. The gas adsorption and fluorescent properties of compound 1 were also investigated.
