Two new Cu (II) phenanthroline succinic acid ternary complexes were synthesized, namely [Cu (phen) 2L] (H2L) · 5H2O (1) and [(phen) 2CuLCu (phen) 2] (1) a = 10.282 (3), b = 12.141 (3), c = 14.233 (3) (2) °, γ = 84.29 (2) °, V = 1690.7 (9) 3, Z = 2, R = 0.1021, wR2 = 0.1387; a = 12.943 (2), b = 14.436 (2), c = 17.974 (3), α = 75.128 (9) °, β = 69.030 (9) °, γ = 69.02 (1) °, V = 2896.2 ) 3, Z = 2, R = 0.0976, wR2 = 0.2240. Structural analysis shows that each Cu atom forms with 4 N atoms belonging to 2 phenanthroline ligands and 2 O atoms from succinate The complex octahedron CuN4O2 with a coordination number of 6 forms a one-dimensional supramolecular chain parallel to the [011] direction through the aromatic ring stacking between the coordination molecules in the complex (1), and the supramolecular chains pass through the hydrogen of the crystal water molecules Bond to form a two-dimensional layer, and then stacked to form a one-dimensional tunnel and three-dimensional framework, succinic acid molecules and the rest of the crystal water molecules located in the tunnel.Complexes (2) Succinate bridged binuclear cations with aromatic ring accumulation The role of forming a (010) plane parallel to the positive two-dimensional layer, C4H 4O42- ion and crystal water molecules located in the positive layer and form a negative two-dimensional network layer.
