Two New Salts Based on Bis(1,2,5-thiadiazole-3,4-dithiolate)nickelate Anion with Benzylpyridinium Derivatives: Syntheses, Crystal Structures and Properties

摘要

Two new salts based on [Ni(tdas) ₂ ] 2 a?? (tdas 2 a?? = 1, 2, 5-thiadiazole-3,4-dithiolate) anion with substituted benzylpyridinium cation, [BzPy][Ni(tdas) ₂ ] (1) and [NO ₂ BzPy] ₂ [Ni(tdas) ₂ ] (2), have been prepared by reaction of Na ₂ tdas, NiCl ₂ .6H ₂ O, and 1-Rbenzylpyrid-inium bromide [RBzPyBr, R = H(1), NO ₂ (2)]. Single-crystal X-ray diffraction analyses indicate that the two salts crystallize in a monoclinic system with space group C ₂/c, but the stacking modes of the anions and the cations are different. Some intra-molecular contacts such as p?· ?· ?· ??, ?? ?· ?· ?· ??, or Ca??H ?· ?· ?· N weak interactions in 1 and 2 play important roles in the molecular stacking and generate a 2D structure. In addition, IR, UV, MS, molar conductivities and effect on crystal structures 1 and 2 are successively described.View full textDownload full textKeywordsbis(1,2,5-thiadiazole-3,4-dithiolate)nickelate salts, crystal structures, spectra, substituted benzylpyridinium, weak interactionsRelated var addthis_config = { ui_cobrand: "Taylor & Francis Online", services_compact: "citeulike,netvibes,twitter,technorati,delicious,linkedin,facebook,stumbleupon,digg,google,more", pubid: "ra-4dff56cd6bb1830b" }; Add to shortlist Link Permalink http://dx.doi.org/10.1080/15533170903492663
