A Novel Dinuclear Copper(ll) Complex:Synthesis, Crystal Structure, Properties and Hirshfeld Surface Analysis

摘要

A novel copper complex [Cu2(L)(DMF)2] (1,n4L =(1Z,N'Z)-3,5-dibromo-N'-((3,5-dibromo-2-hydroxyphenyl)(hydroxy)methylene)-2-hydroxybenzohydrazonic acid which was synthesized by in-situ oxidation reaction derived from H2hdb (H2hdb =6,6'-((1E,1'E)-hydrazine-l,2-diylidenebis (methanylylidene)) bis(2,4-dibromophenol)) has been synthesized and characterized by IR,elemental analysis (CHN),TG and single-crystal X-ray diffraction.The single crystal belongs to monoclinic system,space group P21/c with a =13.538(1),b =3.912(1),c=23.778(1) (A),β =105.232(5)°,Mr =857.08,V=1214.9(1) (A)3,Z =2,Dc =2.343 g/cm3,F(000) =824,μ =8.375 mm-1,R =0.0566,and wR =0.1610.Compound 1 displays weak anti-ferromagnetic interactions through aη1∶η1∶η1∶η1∶η1∶η1∶μ2-L4-bridging mode.Hirshfeld surface analysis revealed that complex 1 was supported mainly by Br….H and H…H intermolecular interactions.
