Synthesis, structure and photophysical properties of two transitional metal supramolecular complexes
摘要:
Two supramolecular complexes: [Co(2,6-PDC)(Hdmpz)(3)]center dot H2O (1) and [Zn(2,6-PDC)(Hdmpz)(2)] (2) {2,6-PDC = pyridine-2,6-dicarboxylic acid, Hdmpz = 3,5-dimethylpyrazol}, self-assembles via O-H center dot center dot center dot O and N-H center dot center dot center dot O hydrogen bondings into supramolecular networks, which are characterized by elemental analyses. IR spectra and single crystal X-ray diffraction analysis. Both of them consist of two-dimensional networks that are stacked together by typical hydrogen bonding interactions (i.e. O-H center dot center dot center dot O and N-H center dot center dot center dot O). which often play important roles in the formation of low-dimensional into high-dimensional supramolecular networks. In addition, quantum chemistry calculations and surface photovoltage spectroscopy are performed firstly with the complexes. (C) 2010 Elsevier B.V. All rights reserved.
