Abstract The title compound, Cu2C17H16O2.5Cl2, is a copper(II) complex, in which each dimeric unit has two copper atoms bridged by a pyrazolato ligand, a di(2-pyridyl)]methane ligand, and an oxygen atom from the modified methylene group that links the two pyridine rings (O-C-O-CH2CH3). The complex crystallizes in the monoclinic groupP21/n,a=7.7330(1),b=19.589(6),c=13.123(2)Å,β=95.020(0)°,V=1980.3(7)Å3,Z=4,F w=514.3,D Do =1.725 g cm−3λ(MoKα)=0.71073 Å,F(000)=1032,μ=2.44 mm−1, R=0.044 for 2209 observed reflections,Rw=0.047,s=0.086. Each dimer is linked to the next unit by long chlorine bonds (Cu(2′)-Cl(1)=2.846(2)Å). These tetrameric units form zigzagged chains through copperchlorine bonds of 3.380(2)Å. The copper(II) complex presents antiferromagnetic behavior withT m=161 K.
