Structure, magnetic properties and DFT calculations of azido-copper(ii) complexes with different azido-bonding, nuclearity and dimensionality
Four bridged-azido Cu(II) complexes were synthesized and structurally characterized: [Cu2(Et3en)2(μ1,1-N3)2(N3)2] (1), [Cu2(ip2en)2(μ1,1-N3)2(N3)2] (2), catena-[Cu2(Et2Meen)2(μ1,3-N3)3]ClO4 (3) and catena-[Cu(ambza)(μ1,1,3-N3)2] (4), where Et3en = N,N,N′-triethyl-1,2-diaminoethane; ip2en = N,N′-diisopropyl-1,2-diaminoethane; Et2Meen = N,N-diethyl-N′-methyl-1,2-diaminoethane; and ambza = 2-aminobenzylamine. Single crystal X-ray crystallography revealed that complexes 1 and 2 are dinuclear with doubly bridged μ1,1-N3, whereas complexes 3 and 4 constitute polymeric species with an alternative sequence of single and double μ1,3-N3 bridges for 3 with a 1D chain, and triple μ1,1,3-bridging azide in 4 with a 2D extended structure. Variable temperature magnetic susceptibilities over the temperature range of 2–298 K revealed a weak antiferromagnetic coupling (J = −1.8 cm−1) for 1, and a ferromagnetic coupling with J values of 7.0 and 7.7 cm−1, respectively, for complexes 2 and 4, respectively. Compound 3 shows a new topology for Cu(II) alternating chains [Cu(1)(μ1,3-N3)2Cu(1′)]-(μ1,3-N3)-[Cu(2′)(μ1,3-N3)2Cu(2′′)]-(μ1,3-N3)-[Cu(1)(μ1,3-N3)2Cu(1′)]-… Three different coupling constants were obtained through a fitting procedure and by DFT calculations.

Metal ions directing the geometry and nuclearity of azido-metal(ii) complexes derived from bis(2-(3,5-dimethyl-1H-pyrazol-1-yl)ethyl)amine
The reaction of a methanolic solution containing M(ClO4)2·nH2O (M = Cu, Ni, Zn or Cd) or CoCl2·6H2O with bis(2-(3,5-dimethyl-1H-pyrazol-1-yl)ethyl)amine (bedmpza) in the presence of NaN3 afforded the complexes [Cu(bedmpza)(μ1,1-N3)]2(ClO4)2 (1), [Ni(bedmpza)(N3)(μ1,1-N3)]2·1.5H2O (2), [Co(bedmpza)(N3)2] (3), [Zn(bedmpza)(N3)]ClO4 (4) and [Cd(bedmpza)(N3)(μ1,1-N3)]2·1.5H2O (5). The five complexes were characterized by spectroscopic techniques and their molecular structures were determined by single crystal X-ray crystallography. The two mononuclear complexes 3 and 4 display distorted TBP and tetrahedral geometry, respectively with the azide ions acting as monodentate ligands. Doubly bridged end-on-azido dinuclear complexes were obtained in the remaining compounds. Compounds 2 and 5 are isomorphic with distorted octahedral geometry, whereas distorted square pyramidal geometry was determined in the Cu(II) complex 1. The magnetic properties for complexes 1 and 2 were investigated by measuring the magnetic susceptibilities at variable temperatures (300–2 K). The Ni(II) complex exhibits moderate ferromagnetic coupling, whereas [Cu(bedmpza)(μ1,1-N3)]2(ClO4)2 (1) which contains two crystallographic independent dinuclear subunits in the unit cell, with different Cu–N(N3)–Cu bond angles, reveals different signs in the magnetic coupling. The complex represents the first example in the literature that has simultaneously two moieties with ferro- (J = 15.4 cm−1) and antiferromagnetic (J = −18.9 cm−1) interactions.
