Single crystal X-ray structure analysis reveals that the two complexes possess distinct three-dimensional (3D) framework structures and can be topologically described as a 3-connected srs (SrSi2)-type net and a 4-connected cds (CdSO4)-type net, respectively. Both tetrazolate and azide groups also have different linkage modes in the two complexes. 1 contains end-on (EO) type azide bridges and 3-connected tetrazolate, while 2 possess end-to-end (EE) azide linkers and 2-coordinated tetrazolate. Magnetic measurements indicate that antiferrimagnetic interactions dominate between Cu(ii) ions in the two complexes with the corresponding magnetic coupling constant being J = -41.0 cm-1 in 1 and J = -8.62 cm-1 in 2.7 p.application/pdfeng(c) Xie, Ya-Bo et al., 2015LligandsEstructura cristal·lina (Sòlids)Propietats magnètiquesLigandsLayer structure (Solids)Magnetic propertiesinfo:eu-repo/semantics/article6550102020-05-12info:eu-repo/semantics/openAccess
