  Copper(II) azide complexes of 1-alkyl-2-(arylazo)imidazoles: Structure and magnetism

  摘要：

  Tetranuclear Cu(II)-azido complexes of the composition [Cu(RaaiR')(N-3)(2)](4) have been synthesized by reacting 1-alkyl-2(arylazo)imidazole (RaaiR'), Cu(OAc)(2)center dot H2O and NaN3 in 1:1:2 mole proportion [RaaiR'; R = H (3), Me (4); R' = Me (a), Et (b)]. The structure of [Cu(HaaiMe)(N-3)(2)](4) (3a) has been confirmed by an X-ray diffraction study. The tetranuclear copper core is generated by dimerisation via mu(1,1)-N-3 of two dimer units. In each dimer one copper centre is five-coordinated (CuN5) and the other one is six-coordinated (CuN6). Variable temperature magnetic measurements of 3a show the occurrence of ferromagnetic (J(1) = +25.3 cm(-1)) and antiferromagnetic (J(2) = -4.7 cm(-1)) interactions through the double and single end-on azido bridges, respectively. Upon addition of excess ligand, a 2-methoxy ethanol solution of the tetranuclear complex fragmented into a mononuclear copper(II) complex of the formula [Cu(RaaiR')(2)(N-3)(2)], and in one case, [Cu(HaaiEt)(2)(N-3)(2)], the structure was established by X-ray diffraction.
