It crystallizes in monoclinic system with space group Pljc. The crystal data are: a=1.087 23(19) nm, b= 1.3601(2) nm, c=1.3596(2) nm,β=105.433(2)°, Z=2, V=1.9380(6) nm3,μ=1.157 mm"1, Dc=1.511 g-cm-3, F(000)= 916, R1=0.033 2, wR2=0.089 1. In the title complex, neutral Cu(II) ion is four coordinated with distorted square planar geometry. The complex formed the dimeric unit through π-π stacking and Cu---N weak interactions. Every two adjacent dimeric units are linked by Cu--O weak interactions to generate a one-dimensional chain. The preliminary biological activity tests showed that antibacterial activity of the complex was significantly improved. CCDC: 855040.
