Presented here are two open-framework zinc phosphites, namely, Zn(dabco)_0.5(HPO₃) (SCU-18) and Zn₄(Hdabco)₂(CH₃COO)₂(HPO₃)₄ (SCU-20), where dabco = 1,4-diazabicyclo[2.2.2]octane. SCU-18 features a rare 3-connected inorganic skeleton with a chiral qtz-h topology. It contains 18-membered-ring (18 MR) channels displaying porosity and second-harmonic-generation response. SCU-20 has a bnn topology containing large 20 MR channels that shows a strong blue emission as a result of excitation at 375 nm.
