Synthesis and Crystal Structure of a Helical Complex [Zn(C_(28)H_(20)N_4O_2)(CH_3OH)]

Haiyan Li

Abstract

The complex, [Zn(C28H20N4O2)(CH3OH)] was synthesized and characterized by elemental analysis and IR spectroscopy. The single crystal structure analysis shows that the complex exhibits a single-stranded helix with the Zn(II) atom having a distorted trigonal bipyramidal configuration. Edge-to-face and edge-to-edge π…π stacking interactions and C-H…π interactions between the aromatic rings and O-H…O hydrogen bonds lead to a three-dimensional network in the crystal structure.Crystal data for the complex: triclinic, space group P1-with a=0.9303(2)nm,b=1.0413(2)nm,c=1.4625(3)nm,α=96.340(10)°,β=103.160(10)°,γ=112.500(10)°,V=1.2434(4)nm3,Z=2,dc=1.447g·cm-3,T=293(2)K,μ=1.027mm-1.F(000)=560,R1=0.0463,wR2=0.0941[I2σ(I)].
