title: Structure of two azide salts of a copper(II) macrocycle and magnetic properties of Cu(14ane)Cu(N3)4.
abstract: 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 micro(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)]BF(4) contains [Cu(14ane)N(3)]+ cations with elongated square pyramidal geometry. The BF(4)(-) anions are weakly coordinated in the sixth coordination site of the cations.
