Hydrogen bonding effects on topological structures of two supramolecular transition metal coordination complexes based on organosulphonate ligands
摘要:
The syntheses, X-ray crystal structures and topological analyses of two supramolecular coordination complexes, [Co(H2O)(4)(Ps)(2)] 1 and [Cu(H2O)(2)(Ps)(2)] 2 (Ps(-) = pyridine-3-sulfonic anion), are reported. Although the basic coordination environments and patterns around the metal centers of 1 and 2 are similar, the overall topologies of the two complexes are very different due to the formation of distinct hydrogen bonding interactions resulting from organosulphonate ligands.
