  Synthesis, crystal structure and spectroscopic study of trans-diazidobis(2,4,6-trimethylpyridine)copper(II) and azidotetrakis(3-ethyl-4-methylpyridine)copper(II) nitrate; [Cu(s-collidine)2(N3)2] and [Cu(β-collidine)4(N3)](NO3)

  摘要：

  Two monomeric complexes of copper(II) azide with 2,4,6-trimethylpyridine and 3-ethyl-4-methylpyridine, namely trans-diazidobis (s-collidine) copper(II) (1) and azidotetrakis-(beta-collidine)copper(II) nitrate (2), have been prepared and characterized by spectroscopic and X-ray crystalographic methods. The spectral results suggest terminal azido ligands in both complexes and ionic nitrate in 2. The structure of 1 consists of isolated polyhedra of trans-[Cu(2,4,6-trimethylpyridine)(2)(N-3)(2)], in which the copper atom is located at the inversion centre and has an almost regular square-planar geometry. The Cu-N(N-3) and Cu-N(L) bond lengths are 1.954(4) and 2.022(3) Angstrom, respectively. The terminal azido ligands are linear and slightly asymmetric [N-alpha-N-beta = 1.184(5) and NbetaNgamma = 1.163(6) Angstrom]. The structure of complex 2 consists of isolated [Cu(3-ethyl-4-methylpyridine)(4)(N-3)](+) cations and NO3- counter anions. The coordination of the copper atom in the cation is a regular tetragonal pyramid with four collidine ligands occupying the basal sites [Cu-N-av = 2.028(10) Angstrom] and a terminal azido ligand at the apical position with a Cu-N distance of 2.193(7)Angstrom.
