Abstract

Abstract : A copper(II) acetate complex with a urea‐functionalized pyridyl ligand, [CuL(OAc)2 ]2 · 2AcOH (1 ) [L = N ‐(3‐ c hlorophenyl)‐ 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. Abstract :
