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
A new complex of N,N?-bis(p-nitrophenyl)-2,2?-(p-phenylene-dioxy) diacetamide DMF monohydrate, C25H25N5O9·H2O (Mr = 557.52), has been synthesized and its structure was determined by X-ray crystallography method. ...A new complex of N,N?-bis(p-nitrophenyl)-2,2?-(p-phenylene-dioxy) diacetamide DMF monohydrate, C25H25N5O9·H2O (Mr = 557.52), has been synthesized and its structure was determined by X-ray crystallography method. The crystal belongs to monoclinic system, space group P21/c with a = 7.2812, b = 25.5894, c = 14.3434 ?, β = 91.110(1)o, V = 2672.0(2) ?3, Dc = 1.386 g/cm3, F(000) = 1168, μ = 0.109 mm-1 and Z = 4. The final R = 0.0493 and wR = 0.1173 for 3389 observed reflections with I > 2σ(I). The asymmetric unit of the title complex consists of monomeric N,N?-bis(p-nitrophenyl)-2,2?-(p-phenyleneioxy)diacetamide 1, one DMF and one water molecule, which are incorporated during recrystallization. The molecules are linked into a three-dimensional network by π…π interactions as well as intermolecular interactions among DMF, water molecule and 1.展开更多
