Synthetic open-structured materials attract increasing attention for wide applications in catalysis, ion-exchange or intercalation. Metal phosphates are possibly the fastest expanding group of open-framework inorganic materials in the past decade. The structural diversity that stemmed from the variable coordination number and oxidation states has directed to the extensive expansion of open-framework metal phosphates. Since the bivalent metal phosphates (+2, +5) are associated with the same total charge as aluminosilicate zeolites (+3, +4), phosphate-based framework structures containing bivalent metals are considerably pursued. After the discovery of the first open-framework zincophosphate with zeolite topologies reported by G. D. Stucky, a great deal of effort has been devoted to isolating novel open-structures within this system. And this compound group has experienced extraordinary expansion in terms of the diversity of their structures and compositions. Zincophosphates with zero-, one-, two-, and three-dimensional architectures have been isolated, in which an eye-catching result is the gigantic pore structure with 24-membered rings in ND-1. This variety was achieved by varying a number of factors that can influence the structure, including template, pH, solvent, reaction temperature, additives, zinc source and others. On the other hand, the pursuit of chiral molecular sieves is of great interest with respect to the applications in enantioselective separation and syntheses. However, only a few inorganic chiral frameworks were known up to now. For the syntheses of open-structured crystals, both alkali cations and organoamine are used as structure directing reagent separately in the literatures. Although there are some compound containing both of them, systematically investigation of the co-template effect of alkali cations and organoamines is seldom. Our group has focused on metal phosphate open-structures for many years. Recently, we are interest in exploring new open-framework metal phosphates co-templated by alkali cation and organoamine. This approach has successfully yielded a new zincophosphate openstructure, Na[H2TETA]0.5[ZnPO4]2·0.5H2O (TETA = triethylenetetraamine) or TJPU-1 (TJPU = Tianjin Polytechnic University), with the zeolite CZP topology. This compound contains left-handed chiral channels along its c axis. Here we report its synthesis and crystal structure. Experimental Section
