Abstract A mixed ligand 1∶2 complex of copper(II) azide with 3,5-lutidine, namely di-μ(1,1)-azido-diμ(0,0)-nitrato)tetrakis(3,5-lutidine)dicopper(II) has been prepared and characterized by X-ray crystallographic and spectroscopic methods. The dimeric molecule, which possesses a crystallographic inversion center, contains twoμ(1,1) bridging azido ligands. Each copper(II) atom in the cyclic Cu2N2 unit is further coordinated by two oxygen atoms from twoμ(0,0-nitrato) bridges at Cu-O distances of 2.465(3) and 2.568(3) Å and two nitrogen atoms from the lutidine molecules [Cu-N=2.003(3) and 2.012(3) Å] to give a distorted tetragonal bipyramid. Both azido ligands are linear [N-N-N angle=179.0(4) and asymmetric Nα-Nβ=1.207(4) and Nβ-Nτ=1.135(5) Å]. The azido bridges produce a rather short Cu ⋯ Cu distance of 3.013(2) Å. Infrared and electronic data are presented and discussed.
