Two novel complexes {[Co (Hbtc) (Pyphen) (H2O)]. H2O} n (1) and {[Cd2 (btc) (Pyphen) 2Cl] .2H2O} n 2) (H3btc = trimellitic acid, Pyphen = [2,3-f] pyrazino [1,10] -phenanthroline) was synthesized and characterized by X-ray single crystal diffraction, elemental analysis, Thermogravimetric analysis and fluorescence were characterized. The complex 1 belongs to the triclinic system with space group P1, a = 0.643 44 (13) nm, b = 1.202 9 (2) nm, c = 1.371 6 (3) nm, 90.46 (3) °, γ = 103.54 (3) °, V = 1.027 7 (4) nm3, Z = 2, CoC23H16N4O8, Mr = 535.31, Dc = 1.730 g.cm- -1, F (000) = 546, GOOF = 1.089, R = 0.099 2, wR = 0.249 0; complex 2 belongs to triclinic system with space group P1, a = 0.96893 (10) nm, c = 1.592 21 (14) nm, α = 67.486 ° 10 °, β = 73.158 ° 10 °, γ = 78.468 ° 10 °, V = 1.660 9 nm 2, Z = 2, Cd2C37H23N8O8Cl, Mr = 967.88, Dc = 1.935 g.cm-3, μ (Mo Kα) = 1.432 mm -1, F (000) = 956, GOOF = 1.051, R = 0.077 9, wR = 0.141 2 . Structural analysis shows that complex 1 is an infinite one-dimensional double-stranded structure and complex 2 is a two-dimensional layered structure. In addition, hydrogen bonding and π-π interactions play an important role in strengthening the structure of the complexes.
