Cu(L)Mn(N3)2]n: the first complex containing both macrocyclic oxamido and alternate (mu-1,1 and mu-1,3) azido bridges

A wattle-type heteropolynuclear complex [(CuL)Mn(N(3))(2)](n) (1) (H(2)L = 2,3-dioxo-5,6:15,16-dibenzo-1,4,8,13-tetraazacyclo-pentadeca-7,13-diene), which represents the first system with macrocyclic oxamido and alternate azido bridges, forming a one-dimensional chain structure, has been synthesized and characterized by a low temperature magnetic study. The chains are stacked with interchain hydrogen and lead to the structure of a three-dimensional network.
