Synthesis, crystal structure, and magnetic properties of 1D Azido-bridged copper(II) complex

Abstract

A novel copper(II)-azide complex Of [Cu(2) (DMAP)(2)(mu-1, 1-N(3))(2)(mu-1,3-N(3))(2)](n) (DMAP = 4-(dimethylamino)pyridine) has been synthesized and characterized by IR spectra, X-ray diffraction, elemental analysis, and magnetism measurement. The complex reveals a ID ladder-like chain structure, in which two mu-1,1-N(3) and two p-1,3-N(3) bridges form a dimeric unit Of [Cu(2)(DMAP)(2) (mu-1,1-N(3))(2)(mu-1,3-N(3))(2)] and are then connected to each other from the tail nitrogens of two asymmetric mu-1,3-N(3) bridges to generate a chain structure that stacks in the cell to construct the 3D crystal. The Cu atom is five-coordinated by azide anions to form a distorted square-pyramid of CuN(5) (tau = 0.2667). Magnetic susceptibility of complex exhibits a ferromagnetic interaction between the copper(H) ions through two kinds of azido-bridges.
