Abstract
A novel supramolecular complex, [Na2(2,3-naphtho-15-crown-5)2(NO3)][Cu(NO3)3(H2O)] (1), has been prepared and characterized by X-ray single crystal diffraction. The complex crystallizes in the triclinic system, space group Pī, with a = 11.233(6), b = 13.342(7), c = 16.601(8) Å, α = 89.836(7), β = 79.132(8), γ = 66.545(7)°, V = 2234(2) Å3, Z = 2 and final R 1(wR 2) = 0.0467(0.1164). Novel coordination features and supramolecular architectures are found in the solid state of 1. Two [Na(2,3-naphtho-15-crown-5)]+ cations containing two different sodium coordination numbers (six and seven) are bridged by a tridentate nitrate group, to form a larger complex cation, [Na2(2,3-naphtho-15-crown-5)2(NO3)], which is assembled into a novel 1D zigzag chain-like structure through aromatic C–H ··· π interactions.
