A copper(II) coordination polymer with alternating double EO-azido bridges and mixed EO-azido/alkoxo double bridges

A novel one-dimensional (1D) copper(II) coordination polymer with alternating double EO-azido bridges and mixed EO-azido/O double bridges, [Cu2(dpk · CH2O)(N3)3]n (dpk · CH2OH = unimethylated diol of di-2-pyridyl ketone) (1), was synthesized and characterized, which represents a new type of 1D CuII magnetic system.
