Nano-sized octa-nuclear nickel cationic complex: self-assembly on supramolecular level
摘要:
Microporous one-dimensional material was synthesized by reacting Ni-9 cluster compound Ni-9(HOOCCMe3)(4)(mu(4)-OH)(3)(mu(3)-OH)(3)(OOCCMe3)(12) with organic ligand 3-(3,5-dimethylpyrazol-1-yl)-6-(3,5-diamino-1,3,4-thiadiazolyl)-1,2,4,5-tetrazine) (L). According to X-ray data, the nano-sized endless tubes of the material consist of stacked cationic Ni(II) octa-nuclear cyclic complexes of formula [Ni-8(mu-OH2)(4)(mu-OOCCMe3)(4)(eta(2)-OOCCMe3)(OOCCMe3)(10)L-4](4) and pivalate anions ordered regularly aside the tubes. The channels of the tubes are filled with acetonitrile molecules forming an inclusion compound. (C) 2002 Elsevier Science B.V. All rights reserved.
