Hydrothermal Syntheses and Crystal Structures of Two Complexes with Cyclic Dimer and 2D Network Structures of 3-Nitrophthalate and N-Donor Ligand
摘要:
Two complexes, [Cd(nphth)(2,2'-bipy)(H2O)]2·2H2O (1) and [Cd(nphth)(4,4'-bipy)(H2O)]n (2) (nphth=3-nitrophthalate, 2,2'-bipy=2,2'-bipyridine, 4,4'-bipy=4,4'-bipyridine), were synthesized by hydrothermal reactions and structurally characterized. Complex 1 crystallizes in triclinic with space group P1, a=0.7599(4), b=1.0551(6), c=1.2448(6) nm, α=88.96(2), β=75.40(2), γ=76.76(2)°, V=0.9393(9) nm3, Z=1, Dc=1.816 Mg/m3, F(000)=512, μ=1.217 mm-1, S=0.946, the final R=0.0238 and wR=0.0631. Complex 2 crystallizes in monoclinic, space group P21/c, a=0.737(5), b=2.338(1), c=1.0030(6) nm, β=96.359(9)°, V=1.803(2) nm3, Z=4, Dc=1.826 Mg/m3, F(000)=984, μ=1.260 mm-1, S=1.016, the final R=0.0455 and wR=0.1007. Complex 1 exhibits a discrete cyclic binuclear structure and complex 2 possesses a 2D layer structure with cyclic binuclear unit. The fluorescent spectrum study shows that complex 1 exhibits fluorescent emission in the solid state at room temperature.

Abstract:
Two complexes, [Cd(nphth)(2,2'-bipy)(H2O)]2·2H2O (1) and [Cd(nphth)(4,4'-bipy)(H2O)]n (2) (nphth=3-nitrophthalate, 2,2'-bipy=2,2'-bipyridine, 4,4'-bipy=4,4'-bipyridine), were synthesized by hydrothermal reactions and structurally characterized. Complex 1 crystallizes in triclinic with space group P1, a=0.7599(4), b=1.0551(6), c=1.2448(6) nm, α=88.96(2), β=75.40(2), γ=76.76(2)°, V=0.9393(9) nm3, Z=1, Dc=1.816 Mg/m3, F(000)=512, μ=1.217 mm-1, S=0.946, the final R=0.0238 and wR=0.0631. Complex 2 crystallizes in monoclinic, space group P21/c, a=0.737(5), b=2.338(1), c=1.0030(6) nm, β=96.359(9)°, V=1.803(2) nm3, Z=4, Dc=1.826 Mg/m3, F(000)=984, μ=1.260 mm-1, S=1.016, the final R=0.0455 and wR=0.1007. Complex 1 exhibits a discrete cyclic binuclear structure and complex 2 possesses a 2D layer structure with cyclic binuclear unit. The fluorescent spectrum study shows that complex 1 exhibits fluorescent emission in the solid state at room temperature.
