CoL(SO4)(0.5) center dot 4H(2)O and MnL2 center dot 2H(2)O (L=1,10-Phenanthroline-4,5-f-triazolate): Synthesis, Crystal Structures and Hydrogen-Bonded Networks

摘要

Two metal complexes of 1H-triazo-4,5-f-1,10-phenanthroline (HL), CoL(SO4)(0.5) center dot 4H(2)O (1) and MnL (2) center dot 2H(2)O (2) have been synthesized on hydrothermal conditions and characterized by elemental analysis, IR spectroscopy and single-crystal X-ray diffraction analysis. Complex 1 was further assembled into a three-dimensional (3D) supramolecular network through the hydrogen-bonding interactions and inter-molecular pi center dot center dot center dot pi stacking interaction, 2 further assembled into a two-dimensional (2D) layer structure. This result shows that hydrogen-bonding interactions and pi center dot center dot center dot pi stacking interaction play important roles in the formation of coordination networks, especially in the aspect of linking the multinuclear discrete subunits or low-dimensional entities into high-dimensional supramolecular frameworks.
