Abstract

The compounds catena-[diaquadichloridocopper(II)] bis(4-bromo-2-pyridone) (1) and catena-[bis(5-bromo-2-pyridone)dichloridocopper(II)] (2) have been prepared and characterized crystallographically. Both show bichloride bridged chains of Cu(II) ions with coordinated water molecules in the axial sites for 1 and coordinated 5-bromo-2-pyridone molecules in the axial sites for 2. 1 incorporates two 4-bromo-2-pyridone molecules co-crystallized in the lattice. Variable temperature magnetic susceptibility measurements for 1 indicate the presence of weak antiferromagnetic interactions [J/k_B = −7.06(5) K] similar to copper(II) chloride dihydrate, but without that compound’s significant inter-chain interactions and Néel transition.
