The compound crystallized in the Monoclinic space group P2（1）/c, with cell parameters, a=0.78410（9） nm, b=1.54744（2） nm, c=0.81418（1） nm, β=105.8150（1）°, V=0.95049（2） nm3 and Z=4. The connectivity of the ZnO4 tetrahedron and HPO3 pseudo pyramid resulted in inifinite corner-sharing 4-membered ring chains, which were further linked by the protonated amine molecules to form a 3D structure via hydrogen bonds. To the best of our knowledge, this is the first existence of a zincophosphite with the anionic framework composition of [Zn（HPO3）（H2PO3）]-. The compound exhibits intense photoluminescence at room temperature.展开更多

Its single-crystal structure refinement has shown the zincophosphite with the composition NH3+ (CH2)(6) NH3+ [Zn(HPO3)(2)](2-), M-r = 343.55. It crystallizes in monoclinic, space group C2/c (No.15), a=2.2391 nm, b=0.8695 nm, c=0.7919 nm, beta = 101.062(6)degrees, V= 1.513 nm(3), D-c=1.508 kg/m(3), Z=4, F(000)=712,mu= 1.849 mm(-1), R-1=0.0416, wR(2)=0.1023. This phase exhibits infinite inorganic chains of vertex-linked ZnO4 and HPO3. Via the electrostatic attraction, 1,6-hexainethylenediamine cations and inorganic chains construct a novel interesting two-dimensional inorganic-organic network.展开更多
