Structure and magnetism of two heteropolynuclear complexes containing both macrocyclic and azido ligands

The two complexes of formula [Co2(CuL)4(μ-N3)4]·2CH3OH 1 and [Mn(NiL)2(N3)2] 2 (CuL and NiL, H2L = 2,3-dioxo-5,6,14,15-dibenzo-1,4,8,12-tetraazacyclo-pentadeca-7,13-dien), have been synthesized and structurally determined. The magnetic susceptibility data of 1 was analyzed, magnetic measurements show an antiferromagnetic exchange interaction between Cu(II) and Co(II) ions.
