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. |
