Synthesis and crystal structure of a new polynuclear complex with a monomer of (3,4,9,10‐dibenzo‐1,12‐diaza‐5,8‐dioxacyclopentadecane)‐copper(II) (μ‐C1) 2 zinc(II) chloride

A polynuclear complex containing a monomer of Cu(II)‐Zn(II) heterobinuclear unit was synthesized and characterized by IR spectra and magnetic moment. The crystal and molecular structure of the complex, CuZnC 19 H 24 Cl 4 N 2 O 2 , was determined by X‐ray diffraction, it crystallized in monoclinic, P 2 1 / m, α = 8.812 (2), b = 15.972(3), c = 8.831(1) Å, β = 114.33(1) ° , V = 1132.4Å 3 , Z = 2, D e = 1.710 g/ cm 3 ,γ(MoK α ) =0.71073 å, μ = 25.227 cm −1 , R = 0.051. R w = 0.063 for 1130 observed reflections with I >3α( 1 ). The coordinated octahedra of Cu(II) and tetrahedra of Zn(II) via bridging CI atoms form a single chain polynuclear complex. The Cu, Zn and bridging Cl atoms are located on the crystallographic symmetry plane m which is perpendicular to 2N and 2O donor plane.
