A copper(II) acetate complex with a urea‐functionalized pyridyl ligand, [CuL(OAc)₂]₂·2AcOH (1) [L = N‐(3‐chlorophenyl)‐N'‐(3‐pyridyl) urea], was synthesized by the reaction of L with Cu(OAc)₂ in methanol. A zigzag‐shaped hydrogen bond chain of L is obtained via urea N–H···N_pyridyl interactions, and a two‐dimensional hydrogen bond network structure is further formed through the C–H···O interaction. In the complex 1, a paddle‐wheel structure is generated by Cu···O_acetate interactions and Cu···N_pyridyl interactions. Furthermore, hydrogen bonding chain structure is extended through weak C–H···O hydrogen bond interactions. Through ultraviolet‐visible (UV/Vis) spectroscopy, the acetate binding properties of L in solution were also evaluated. Variable temperature magnetic susceptibility measurement indicates that the metal complex 1 displays antiferromagnetic coupling property.
