Structure of two azide salts of a copper(II) macrocycle and magnetic properties of Cu(14ane)Cu(N-3)(4)
Synthesis of azide complexes with the copper(II) macrocycle complex Cu(14ane)(2+) (where 14ane = 1,4,8,11-tetraazacyclothetradecane) has yielded two compounds. Cu(14ane)Cu(N-3)(4) contains mu(1,3)-azido bridged chains of Cu(14ane)(2+) cations and Cu(N-3)(4)(2-) anions. Magnetic studies reveal the presence of ferromagnetic interactions within the chains with J/K = 0.635(4) K. [Cu(14ane)N-3]BF4 contains [Cu(14ane)N-3](+) cations with elongated square pyramidal geometry. The BF4- anions are weakly coordinated in the sixth coordination site of the cations.
