Synthesis and crystal structures of supramolecular compounds: [Cu(mpca)₂(H₂O)] · 3H₂O and [Cu₂(mpca)₂(pyr)₄]

摘要

A new chelate ligand, 5-methyl-1H-pyrazole-3-carboxylic acid (mpca), has been synthesized. This ligand reacts with cupric sulfate to give two supramolecular compounds [Cu(mpca)₂(H₂O)] · 3H₂O (1) and [Cu₂(mpca)₂(pyr)₄] (Pyr = pyridine) (2), which were characterized by elemental analysis and X-ray crystal diffraction. Helical water chain and strong π-π interaction are important for the stability of the 3-D structure of these supramolecules.View full textDownload full textKeywordsPyrazole, Water chain, Hydrogen bondsRelated 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/10.1080/00958970903156566
