The title compound, a-poly[{[N-(2-aminoethyl)-1,2-ethanediamine-N,N',N
'']copper(II)}-mu-succinato-O,O':O ''], [Cu(C4H4O4)(C4H13N3)](n), has
a polymeric structure in which the central Cu atom is coordinated by
three N atoms from the diethylenetriamine molecule, two O atoms from t
he succinate ion and one O atom from the succinate ion of the adjacent
complex unit. The coordination polyhedron around the Cu atom can be r
egarded as a severely distorted octahedron.
