Variation in crystalline architectures through supramolecular interactions in copper(II) complexes with tridentate N2O donor Schiff bases
Författare
Summary, in English
Three copper(II) complexes, [Cu(L-1)(H2O)(ClO4)]0.5H(2)O (1), [Cu(L-2)(H2O)(ClO4)]0.5H(2)O (2), and [Cu(L-2)(NCNC(OCH3)NH2)]ClO4 (3), where HL1=4-bromo-2-(-(quinolin-8-ylimino)methyl)phenol and HL2=1-(-(quinolin-8-ylimino)methyl)naphthalen-2-ol, have been prepared and characterized by elemental analysis, IR, UV-vis and fluorescence spectroscopy and single-crystal X-ray diffraction studies. The copper(II) centers assume five-coordinate square-pyramidal geometries in 1 and 2, whereas square planar copper(II) is present in 3. A methanol molecule has been inserted in the pendant end of the ligated dicyanamide in 3. Various supramolecular architectures are formed by hydrogen bonding, , C-H, and lp interactions.
