Flux synthesis of two new organically templated zinc phosphites with different 3,4-connected frameworks

Two new organically templated zinc phosphites, H2depda·Zn3(HPO3)4 (1) and H2dmpda·Zn3(HPO3)4 (2), have been synthesized under flux conditions, where depda = N,N-diethyl-1,3-propanediamine and dmpda = N,N-dimethyl-1,3-propanediamine. The two compounds have different (3,4)-connected inorganic frameworks constructed by strictly alternating ZnO4 tetrahedra and HPO3 pseudo pyramids. The presence of large 12-ring channels in the two open-framework structures is noteworthy.
