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 structure was determined by single-crystal X-ray diffraction and further characterized by FTIR, elemental analysis, powder X-ray diffraction and thermogravimetric analysis. Crystal data for 1: Mr = 486.88, monoclinic, space group P21/c with a = 10.2287(11), b = 9.7624(11), c = 16.1686(18) , b = 92.573(2), V = 1612.9(3) 3, Z = 4, Dc = 2.005 g/cm3, F(000) = 984, = 3.314 mm-1 and S = 1.152. The final R = 0.0473 and wR = 0.1121 for 2456 observed reflections with I > 2s(I). The inorganic layer consisting of four- and eight-membered rings is constructed of alternating ZnO4 tetrahedra and HPO3 pseudo pyramids by sharing vertices. The organic template molecules reside in the interlayer region and interact with the inorganic network through H-bonds.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
