Novel hydrogen-bonded supramolecules derived from 4-pyridin-2-yl-pyrimidine-2-sulfonate with transition metals
摘要:
Reactions of 4-pyridin-2-yl-pyrimidine-2-sulfonate (NaL) with a few transition metal salts, which resulted in the formation of mononuclear complexes 1-3 ([M(L)(2)] H2O, M = CO2+, Ni2+, Zn2+), assembled into 3D hydrogen-bonded supramolecules. The ligand offers N,N,O-chelation and the geometry around each metal atom is distortedly octahedral. The sulfonato oxygen atoms of the ligand are engaged in intermolecular hydrogen-bonding, leading to the formation of hydrogen-bonded supramolecules. (c) 2006 Elsevier B.V. All rights reserved.
