Reaction of [15]crown-5 with erbium nitrate and a range of nickel salts results in the formation of the hydrogen-bonded chain species [Er(NO3)3(H2O)3]·[15]crown-5⋅H2O (3), [Ni(H2O)6]Br2⋅[15]crown-5·2 H2O (4), [Ni(H2O)6](ClO4)2·[15]crown-5⋅2 H2O (5), [Ni(H2O)6](NO3)2·[15]crown-5⋅2 H2O (6) and [{Ni(H2O)4}2(μ-Cl)2]Cl2·[15]crown-5 (7). Complexes 3–5 exhibit low symmetry structures with 2–4 unique crown ether molecules, whereas 6 and 7 are more symmetrical. The factors contributing to this behaviour are discussed within the wider context of [15]crown-5 structures in the Cambridge Structural Database.
