Two unusual complexes[Cd2(Do)4(H2O)2Cl](PW12O40)2H2O(1)and[Ag4(Do)6(PW12O40)][Ag(Do)2]2(PW12O40)2H2O(2)were hydrothermally synthesized by the combination of two different metallic salts,Keggin-type polyoxometalate and 1,10-phen-5,6-dione(Do),and characterized by elemental analyses,inductively coupled plasma analyses,infrared spectra,X-ray photoelectron spectroscopy,thermal gravimetry,photoluminescent spectra and single-crystal X-ray diffraction analyses.Crystal 1 is of monoclinic,space group P21/n with a=12.383(3),b=18.326(4),c=16.437(3),β=90.29(3)o,V=3730.1(13)3,Z=2,Cd2C48H32N8ClO52PW12,Mr=4050.24,Dc=3.604 g·cm-3,μ(MoKα)=19.145 mm-1,F(000)=3608,GOOF=1.168,the final R=0.0569 and wR=0.0745 for 5715 observed reflections(I>2σ(I)).Crystal 2 is of triclinic,space group P1 with a=13.959(5),b=16.972(5),c=17.647(5),α=85.970(5),β=81.353(5),γ=86.316(5)o,V=4117(2)3,Z=1,Ag6C120H64N20O102P2W24,Mr=8539.47,Dc=3.444 g·cm-3,μ(MoKα)=17.511 mm-1,F(000)=3828,GOOF=1.033,the final R=0.0981 and wR=0.1658 for 9906 observed reflections(I>2σ(I)).Structural analyses show that complex 1 has a zero dimensional structure,which is further assembled into a one-dimensional ladder-like structure through hydrogen bonds.Complex 2 possesses a one-dimensional chain structure.Furthermore,solid-state luminescent spectra of complexes 1 and 2 indicate red and green fluorescent emission,respectively.
Two unusual complexes [Cd2 (Do) 4 (H2O) 2Cl] (PW12O40) 2H2O (1) and [Ag4 (Do) 6 (PW12O40)] [Ag (Do) 2] 2 by the combination of two different metallic salts, Keggin-type polyoxometalate and 1,10-phen-5,6-dione (Do), and characterized by elemental analyzes, inductively coupled plasma analyzes, infrared spectra, X-ray photoelectron spectroscopy, thermal gravimetry, photoluminescent spectra and single-crystal X-ray diffraction analyzes. Crystal 1 is of monoclinic, space group P21 / n with a = 12.383 (3), b = 18.326 (4), c = 16.437 (3) o, V = 3730.1 (13) 3, Z = 2, Cd2C48H32N8ClO52PW12, Mr = 4050.24, Dc = 3.604 g · cm-3, μ (MoKα) = 19.145 mm-1, F = 1.168, the final R = 0.0569 and wR = 0.0745 for 5715 observed reflections (I> 2σ (I)). Crystal 2 is of triclinic space group P1 with a = 13.959 (5), b = 16.972 = 17.647 (5) α = 85.970 (5) β = 81.353 (5) γ = 86.316 (5) o V = 4117 (2) 3 Z = 1 Ag6C120H64N20O102P2W24 Mr = 8539.47 Dc = 3.444 g · Cm-3, μ (MoKα) = 17.511 mm -1, F (000) = 3828, GOOF = 1.033, the final R = 0.0981 and wR = 0.1658 for 9906 observed reflections (I> 2σ (I)). Structural analyzes show that complex 1 has a zero dimensional structure, which is further assembled into a one-dimensional ladder-like structure through hydrogen bonds. Complex 2 possesses one one- dimensional chain structure. Morerther, solid-state luminescent spectra of complexes 1 and 2 indicate red and green fluorescent emission, respectively.
