Highly stable copper(I)-olefin coordination polymers capable of co-existing with water and acid

Under solvothermal conditions, the reactions of trans-3-(4-pyridyl)acrylic acid (4-HPYA) and 1,10-phenanthroline (phen), and trans-3-(3-pyridyl)acrylic acid (3-HPYA) and 2,2′-bipyridine (2,2′-bpy) with Cu(MeCN)4BF4 give rise to two unprecedented stable copper(I)–olefin coordination polymers, {[(phen)(4-HPYA)Cu(I)](BF4)}n (1) and {[(2,2′-bpy)(3-HPYA)Cu(I)](BF4)·H2O}n (2), respectively.
