Synthesis, structure and magnetic property of a 2D grid-like copper(II) complex with end-on azido and pyrazine bridges

Abstract: A 2D grid-like copper(II) complex [Cu(N3)2(pyz)](pyz=pyrazine) (1) has been synthesized and characterized by single crystal X-ray analysis and magnetic measurements. The 2D grid-like network of 1 consists of 1D chain of Cu-pyz units connected by end-on azido bridge. 1 crystallizes in the monoclinic space group C2 with a =15.148(6)Å, b =6.877(2)Å, c =3.4591(12)Å and Z =2. The magnetic investigation showed the presence of an antiferromagnetic interaction between the copper(II) ions mainly mediated through pyrazine bridge. [Copyright &y& Elsevier]
