摘要

Upon controlling coordination sites of a new bipyridinium analogue 4′-(N-carboxybenzyl-4-pyridinio)-2,2′:6′,2″-terpyridine chloride (HL·Cl) with different dosage of perchloric acid, two copper complexes with distinct bridging modes, {[Cu(L)Cl]·ClO₄·3H₂O}_n (1) and [Cu₂(HL)₂Cl₂]·4ClO₄·H₂O (2) have been obtained under hydrothermal condition. Complex 1 features a one-dimensional chain-like structure with mononuclear Cu(II) centers, while 2 is a dichloro-bridged dinuclear Cu(II) complex, which forms one-dimensional supramolecular chain via hydrogen bonding interactions between the carboxylic groups of HL ligands. The magnetic measurement reveals that an antiferromagnetic coupling interaction exists in complex 2.
