The compound 2,4,4,9,11,11-hexamethyl-1,5,8,12-tetraazacyclotetradecane-1,8-diene(1) was synthesized by new method with high yield(95.2%),and its complex with Cu(II) and SCN-was also obtained.The structures of both the ligand and the complex were characterized by IR,elemental analysis,and X-ray diffraction.The crystal of the title compound(2) belongs to monoclinic system,space group P21/n,Mr=501.53,a=1.28883(11) nm,b=1.13462(10) nm,c=1.58128(13) nm,β=102.7430(10)°,V=2.2554(3) nm3,Z=4,d=1.477g/ cm3,F(000)=1052.R1=0.0360,wR2=0.0976[I>2σ(Ⅰ)].The copper atom is five–coordinated with four nitrogen atoms from compound 1 and one nitrogen atom from thiocyanate to form a tetragonal pyramid structure.
