The coordination polymer [Zn(mesaconate)(dpa)](n) (1, dpa = 4,4'-dipyridylamine) has been prepared from the hydrothermal treatment of zinc chloride, dpa, and itaconic acid. An in situ terminal alkene to internal alkene isomerization occurred during self-assembly, unprecedented in coordination polymer chemistry. Single-crystal X-ray diffraction revealed that 1 crystallizes in the acentric space group Aba2, and features a parallel doubly interpenetrated (4,4)-rectangular layer morphology. Interlayer hydrogen bonding mediated by the dpa ligand results in a doubly interpenetrated (3,5)-connected supramolecular lattice with a novel (4(2)6)(4(2)6(5)8(3)) topology. Compound 1 undergoes blue-light emission upon exposure to ultraviolet radiation.
