Self assembly of three new copper coordination polymers based on N-[(3-pyridine)-sulfonyl]aspartate: Synthesis and structure

Resumo

Three new copper coordination polymers [Cu(L) · 6H₂O]_n (I), [Cu₂(L)₂]_n (II), and [Cu(HL)₂]_n (III), where H₂L is N-[(3-pyridine)-sulfonyl]aspartate, have been synthesized and characterized by singlecrystal X-ray diffraction (CIF files CCDC nos. 1435871 (I), 1435872 (II), 1435873 III), elemental analysis and IR spectra. Moreover, the variable-temperature magnetic susceptibility had been studied for complex I. A structural comparison of these polymers suggests that different reaction temperatures play important role in the construction of resulting architectures for I–III.
