A heterometallic polymeric complex: [Cu2(N3)2(medpt)2[Ni(CN)4]]n [medptis bis(3-aminopropyl)methylamine]

The structure of the title compound, catena-poly[[di-micro-azido-kappa(4)N(1):N(1)-bis[[bis(3-aminopropyl)methylamine-kappa(3)N]copper(II)]]-micro-cyano-[dicyanonickel(II)]-micro-cyano], [Cu(2)(N(3))(2)(medpt)(2)[Ni(CN)(4)]](n) [medpt is bis(3-aminopropyl)methylamine, C(7)H(19)N(2)] or [Cu(2)Ni(CN)(4)(N(3))(2)(C(7)H(19)N(3))(2)](n), is a one-dimensional heterometallic covalent chain where Ni(CN)(4)(2-) functions as a molecular ion bridge. The Ni atom sits on the centre of inversion. The chain undergoes hydrogen-bonding interactions, forming a three-dimensional supramolecular network.
