Abstract: The title complexes, {[Co(Hbtc)(Pyphen)(H2O)]·H2O}n (1) and {[Cd2(btc)(Pyphen)2Cl]·2H2O}n (2) (H3btc=1,2,4-benzenetricarboxylic acid, Pyphen=pyrazino[2,3-f][1,10]-phenanthroline) have been hydrothermally synthe-sized and structurally characterized by X-ray single-crystal diffraction, elemental analyses, thermal gravimetry analysis (TGA) and luminescent property. Crystal 1 is of triclinic, space group P1 with a=0.643 44(13) nm, b=1.202 9(2) nm, c=1.371 6(3) nm, α=95.03(3)°, β=90.46(3)°, γ=103.54(3)°, V=1.027 7(4) nm3, Z=2, CoC23H16N4O8, Mr=535.31, Dc=1.730 g·cm-3, μ(MoKα)=0.900 mm-1, F(000)=546, GOOF=1.089, the final R=0.099 2 and wR=0.249 0 for 2 933 observed reflections (I>2σ(I)). Crystal 2 is of triclinic, space group P1 with a=0.968 93(8) nm, b=1.223 82(10) nm, c=1.592 21(14) nm, α=67.486 0(10)°, β=73.158 0(10)°, γ=78.468 0(10)°, V=1.660 9(2) nm3, Z=2, Cd2C37H23N8O8Cl, Mr=967.88, Dc=1.935 g·cm-3, μ(MoKα)=1.432 mm-1, F(000)=956, GOOF=1.051, the final R=0.077 9 and wR=0.141 2 for 4 817 observed reflections (I>2σ(I)). Structural analyses show that the complex 1 presents an infinite one-dimensional polymeric double-chain structure and the complex 2 shows a two-dimensional layered structure. Furthermore, the hydrogen-bonding and π-π stacking interactions play key roles in consolidating the complex structures. CCDC: 829207, 1; 829208, 2. |
