A new 2D structure, Cu(bpe)(ddc) was synthesized by a reaction of hydrated cupric nitrate, 1,2-bis(4-pyridyl)ethane (bpe), 1,10-decanedicarboxylic acid (H2ddc) and triethylamine (tea) via a room temperature diffusion method. The compound with chemical formula C24H32N2CuO4 crystallizes in triclinic space group P1̄, a = 7.944(3) Å, b = 8.714(3) Å, c = 9.366(3) Å, α = 64.55(3)°, β = 86.72(2)°, γ = 73.74(3)°, V = 560.5(3) Å3 and Z = 1. Within the structure, each copper forms four equatorial bonds with two ddc and two axial bonds with two bpe to give rise to a distorted octahedron. The Cu-ddc connections generate a 1D zigzag chain. The chains are further connected via bpe nitrogen at Cu axial positions to result in a 2D layered structure.
