| Abstract: | 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 ··· Npyridyl 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 ··· Oacetate interactions and Cu ··· Npyridyl 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. |
