Abstract

Abstract: Two dicopper complexes containing different exogenous bridges, Cu₂(pfhmp)Br ·2H₂O(1) and Cu₂(pfhmp)C₃H₃N₂ · 2H₂O(2), were synthesized, where pfhmp^3- denotes dehy-drogen anion of N,N-diisonicotinoyl-hydroxy-4-methylisophthalaldehyde dihydrozone.Based on the elementary analysis, IRand molar conductance, the complexes are proposed to have hetero-bridged structures and enolic configuration.The determination of variable-temperature magnetic susceptibility indicates that the variation of exogenous bridge obviously changes magnetic exchanges interaction between two Cu(Ⅱ) ions.
